    Crystal-field splitting of Pr3+ (4f 2) energy levels in GaN (2001)

    Notes: We have calculated the crystal-field splitting of the energy levels of Pr3+ in GaN and have compared these results to an analysis reported recently of the photoluminescence and the cathodoluminescence spectra of Pr3+ implanted in GaN by metal organic chemical vapor deposition on sapphire substrates. The lattice location of Pr in GaN determined recently by the emission channeling technique, provides direct evidence that substitutional Ga sites are thermally stable lattice positions for Pr. The lattice-sum calculations with Pr occupying Ga sites include effective ionic charges, multipole polarizabilities, and structural information also available in the literature. From the calculations, we conclude that the majority of the reported emission spectra is associated with Pr3+ ions in a common site with transitions from excited 3P0 and 3P1 states to crystal-field split multiplets, 3H4 (the ground state), 3FJ, and 1G4. © 2001 American Institute of Physics.

    Thermal expansion coefficient of polycrystalline silicon and silicon dioxide thin films at high temperatures (2000)
    [S.l.] : American Institute of Physics (AIP)

    Notes: The rapid growth of microelectromechanical systems (MEMS) industry has introduced a need for the characterization of thin film properties at all temperatures encountered during fabrication and application of the devices. A technique was developed to use MEMS test structures for the determination of the difference in thermal expansion coefficients (α) between poly-Si and SiO2 thin films at high temperatures. The test structure consists of multilayered cantilever beams, fabricated using standard photolithography techniques. An apparatus was developed to measure the thermally induced curvature of beams at high temperatures using imaging techniques. The curvatures measured were compared to the numerical model for multilayered beam curvature. The model accounts for the variation in thermomechanical properties with temperature. The beams were designed so that the values of Young's moduli had negligible effect on beam curvature; therefore, values from literature were used for ESi and ESiO2 without introducing significant error in curvature analysis. Applying this approximation, the difference in thermal expansion coefficients between αSi and αSiO2 was found to increase from 2.9×10−6 to 5.8×10−6 °C−1 between room temperature and 900 °C. These results suggest that the α for poly-Si thin films may be significantly higher than values for bulk, crystalline Si. © 2000 American Institute of Physics.

    Grain-boundary room-temperature low-field magnetoresistance in Sr2FeMoO6 films (2000)

    Notes: Thin films of (001)-oriented Sr2FeMoO6 have been epitaxially deposited or LaAlO3 and SrTiO3 (001) substrates by pulsed laser deposition. The deposition conditions were optimized. Single-phase Sr2FeMoO6 was obtained in 100 mTorr 99.999% Ar gas at 825 °C. Transport and magnetic data showed a metallic temperature dependence and a saturation magnetization Ms at 10 K of 3.2μB/f.u. However, the Curie temperature TC(approximate)380 K was reduced from 415 K found for tetragonal polycrystalline best ceramics, which lowers Ms at 300 K in the thin films to 1.5μB/f.u. compared to 2.2μB/f.u. in the ceramics. A low remanence was attributed to the presence of antiphase boundaries. A Wheatstone bridge arrangement straddling a bicrystal boundary was used to verify that spin-dependent electron transfer through a grain boundary and not an antiphase boundary is responsible for the low-field magnetoresistance found in polycrystalline samples below TC. © 2000 American Institute of Physics.

    Notes: NdSc3(BO3)4 (NdSB) can be grown as a nonlinear optical crystal having hexagonal (huntite) structure. The crystal has important spectroscopic properties suitable for various applications in photonics. The observed crystal-field splitting of the energy levels of Nd3+(4f3) has been identified based on analyses of the fluorescence, absorption, and excitation spectra obtained at 13, 80, and 300 K. A detailed crystal-field splitting calculation in which initial crystal-field parameters Bnm are established from lattice–sum calculations gives good agreement to the observed splitting. Experimental branching ratios and fluorescence lifetimes are reported and are compared with calculated values. The spectroscopic properties of Nd3+ in NdSB are also compared with values obtained for Nd3+ as a dopant in the nonlinear crystal YAl3(BO3)4. © 2000 American Institute of Physics.

    Evidence for the physical basis and universality of the elimination of particulates using dual-laser ablation. II. Dynamic time-resolved target reflectivity of metals and film growth of Zn (2002)

    Notes: We have presented, in Part I of this series of two articles, the applicability of dynamic melt studies of the surface of a target under pulsed CO2 laser radiation to determine the onset of melt in these targets. Determination of this time and the accurate synchronization of an excimer (KrF) laser to coincide with the onset of melt on the target surface was shown to lead to particulate-free film deposition for Y2O3 and ZnO films. A key feature of the pump–probe reflectivity studies was the dynamic enhancement of the reflected probe signal, indicating the onset of melt. Some metallic targets, depending on the diameter of the precursor powder globules, such as the zinc target used in this study, do not yield such observable enhancements. In this article (Part II) we present the determination of the time for ablation of a variety of metallic targets under pulsed CO2 laser radiation, by monitoring the dynamic target reflectivity. The melt time is either directly determined or, in the absence of observable melt, estimated based on a simple thermal model for the absorption of the laser radiation by the target. Correlation of the calculated melt times with the morphological quality of particulate-free film growth of Zn is demonstrated. The effect of variable CO2 laser fluence on the deposited films is also demonstrated. The universality of applicability of the target reflectivity studies to a wide range of dissimilar materials, as well as the physical basis for the removal of particulates in dual-laser ablation is established. © 2002 American Institute of Physics.

    Notes: We have analyzed the cathodoluminescence spectra of Sm3+ ions implanted and annealed in GaN epilayers. High-resolution emission spectra were obtained at 11 K between 350 and 1050 nm, representing transitions from the 4G5/2 to the 6HJ and 6FJ manifolds of Sm3+(4f5). Emission lifetimes were determined at various temperatures between 7 and 320 K for transitions from 4G5/2 to 6H5/2, 6H7/2, and 6H9/2. Lattice-sum calculations were carried out to determine the crystal-field splitting of the multiplet manifolds. With individual Stark levels and corresponding wave functions identified, the matrix elements for both electric–dipole and magnetic–dipole transitions were calculated between levels. Radiative lifetimes were calculated and compared with experimental lifetimes. High quantum efficiencies are reported. The calculated branching ratios for transitions from 4G5/2 to 6HJ and 6FJ manifolds indicate that transitions to 6H5/2, 6H7/2, and 6H9/2 account for 80% of the total observed emission. © 2002 American Institute of Physics.

    Evidence for the physical basis and universality of the elimination of particulates using dual-laser ablation. I. Dynamic time-resolved target melt studies, and film growth of Y2O3 and ZnO (2002)

    Notes: The application of a dual-laser ablation process, incorporating the addition of a synchronized CO2 laser to the traditional excimer (KrF) laser used for the ablation of targets in thin film deposition, has been previously demonstrated to be effective in the elimination of particulates in films of Y2O3 [J. Vac. Sci. Technol. A 13, 1171 (1995)]. It has been hypothesized that the efficacy of particulate removal is related to phase transformation from the solid to liquid phase prior to excimer laser ablation of the target material. In this series of two articles we present direct physical evidence of the dynamics of the phase transformation occurring on the target surface and its effect on the morphology of film growth. Pump–probe experiments have been conducted using the CO2 laser to probe the dynamic reflectivity of the target surface on the nanosecond timescale. These experiments were conducted for a range of materials spanning a wide range of thermal conductivity including a low thermal conductivity insulator (Y2O3), and a sublimating oxide (ZnO), as well as a high thermal conductivity metal (Zn) to assess the universal applicability of the results. In this article (Part I) the results of these dynamic reflectivity experiments are correlated with previously reported particulate-free deposition of thin films of Y2O3. Similar experiments are conducted for ZnO. In both cases, the reflectivity measurements yielded times for the onset of melt at a variety of CO2 laser fluences. Synchronization of the KrF laser to coincide with the onset of melt resulted in particulate-free film growth. The effect of mistiming on the quality of the deposited film is presented for ZnO. © 2002 American Institute of Physics.
