    Notes: A CuInSe2-based thin film solar cell fabricated by the selenization method was investigated by micro-Raman-spectroscopy. By measuring the depth-profile of spatially-resolved Raman spectra taken from the cross section of the cell, the formation of MoSe2 at the Mo/CuInSe2 interface was confirmed. © 1996 American Institute of Physics.

    Influence of nonstoichiometry on the Urbach's tails of absorption spectra for CuInSe2 single crystals (1996)

    Notes: Optical absorption spectra of CuInSe2 single crystals were measured for the samples with −0.150≤x≤0.053, where x represents a degree of nonstoichiometry in the formula Cu1−xIn1+xSe2. The Urbach's tail was observed for all samples between 90 K and room temperature. The Urbach's energy, which represents an arbitrary intensity of exciton–phonon interaction, was almost constant for the Cu-rich samples (x〈0), while it increased with increasing In composition for the In-rich ones (x(approximately-greater-than)0). Such an increase of the Urbach's energy was explained to be due to enhanced electronic distortion caused by the compositional deviation from stoichiometry in terms of simultaneous influence of electron–phonon interaction and structural disorder. © 1996 American Institute of Physics.

    Preparation and characterization of CuAlxGa1−xSe2 alloy layers grown by low-pressure metalorganic vapor phase epitaxy (1996)

    Notes: CuAlxGa1−xSe2 alloy layers were successfully grown on GaAs(001) by low-pressure metalorganic vapor phase epitaxy. The distribution coefficient of Al was unity. All alloy layers had their c-axis normal to the substrate plane. Exciton resonance energies were determined as a function of x by means of photoreflectance measurements. A quadratic dependence of exciton energies on x was confirmed. The spin-orbit splittings of the epilayers were approximately the same as that of bulk crystals. The magnitudes of crystal-field splittings were larger than that of bulk crystals, and this was explained in terms of residual tensile biaxial strain in the epilayers. The color of the low-temperature photoluminescence (PL) changed from red to crimson, orange, yellow, green, and bluish-purple with increasing x. A peak due to a free-to-acceptor transition was dominant in the PL spectra of the alloy layers. The acceptor ionization energy increased with increasing x, and the result may reflect an increase of the hole effective mass. © 1996 American Institute of Physics.

    Notes: The intrinsic cholinergic nerve supply of the human myometrium was studied by using electrical transmural stimulation and was found to be postganglionic and minimal. The pharmacological findings indicated that the human nonpregnant myometrium possessed sensitive cholinergic muscarinic receptors, but during pregnancy the sensitivity of the muscarinic receptors was markedly reduced. These results support our hypothesis that the human pregnant myometrium is protected from autonomic influence.

    Notes: The thermal expansion of the compound semiconductors CdIn2S4 and CdInGaS4 has been investigated on single crystals between 120 and 570 K. At high temperatures the anharmonic effects in lattice vibrations of the (parallel)c-axis direction in CdInGaS4 is similar to that in the ⊥c-axis direction, and that in CdIn2S4 is similar to that in CdInGaS4 in spite of the diverse crystal structures. The characteristic temperature (corresponding to Debye temperatures) for CdIn2S4 is 175±10 K, and for CdInGaS4 it is 200±10 K ((parallel)c axis) and 161±10 K (⊥c axis), respectively.

    Hydrostatic pressure dependence of the exponential optical absorption in CdInGaS4 (1987)

    Notes: The optical-absorption spectra in the semiconductor CdInGaS4 have been measured precisely at various hydrostatic pressures up to 20 kbar, and analyzed in the region below the fundamental absorption edges. It can be seen that the absorption coefficients plotted semilogarithmically vary linearly with photon energy below the fundamental absorption edges at each hydrostatic pressure. The steepness of the absorption edge is proportional to the inverse of hydrostatic pressure.

    Overview of large helical device diagnostics (invited) : Papers from the thirteenth topical conference on high temperature plasma diagnostics (2001)

    Notes: The Large Helical Device (LHD) is the largest helical machine with superconducting coils. Key diagnostics issues for LHD are: (a) capability for multidimensional measurements because of the nonaxisymmetric toroidal plasma; (b) measurements of the electric field; (c) cross check of fundamental parameters using different methods; (d) advanced measurements appropriate for steady-state operation; and (e) a satisfactory data acquisition system. The design and research and development of plasma diagnostics were carried out taking these issues into consideration. As a result, the present status of diagnostics is described: diagnostics for LHD operation, fundamental diagnostics for plasma performance, diagnostics for physics subjects, innovative diagnostics and diagnostics for long-pulse operation. The LHD experiment started in March, 1998. Since then, the development of diagnostics has kept pace with the experimental campaigns. © 2001 American Institute of Physics.

    Quantum mechanical behavior of an H atom on Cu(111) and Pt(111) (2002)

    Notes: The quantum mechanical behavior of an H atom adsorbed on Cu(111) and on Pt(111) is investigated. The potential energy curves (PECs) for the H atom motion on these surfaces are calculated within the density functional theory, and the adiabatic three-dimensional potential energy surfaces (PESs) are constructed based on the obtained PECs. The wave functions and their energies for the H atom motion on the PESs are calculated within the framework of the variation method. The results show that, in the case of Cu(111), the ground state wave function is strongly localized around the fcc hollow site, the first-excited state wave function is strongly localized around the hcp hollow site, and these states almost energetically degenerate. On the other hand, the second-excited state wave function is delocalized and extends from the fcc hollow site to the bridge site and further to the hcp hollow site. Then, there is a significant energy gap between the first- excited and the second-excited state. In the case of Pt(111), the ground and the first-excited state wave functions are delocalized and extend from the hollow site to the bridge site. The second-excited state wave function further extends over the top site. The energy differences between the ground and the first-excited state, and between the first-excited and the second-excited state are very small. Thus, the H atom adsorbed on Pt(111) has a delocalized nature. © 2000 American Institute of Physics.

    Interactions of atomic hydrogen with Cu(111), Pt(111), and Pd(111) (2000)

    Notes: We calculate the potential energy curves for H adsorption on and absorption in Cu(111), Pt(111), and Pd(111) within the density functional theory. We show stronger dependence of the potential energies on the lateral position of the H atom at the position further from the surface in the case of Pt(111) than one in the case of Pd(111), and no lateral position dependence in the case of Cu(111). Contrary to this, when the H atom comes close to and adsorbs on the surface, the dependence of its adsorption energy (a depth of potential well outside the surface) on the lateral position in the case of Cu(111) is stronger than one in the case of Pd(111), and such dependencies are hardly seen, and the adsorption energies are nearly the same in the case of Pt(111). When the H atom penetrates the first layer of the surface, the activation barrier at a so-called face-centered-cubic hollow site in the case of Pd(111) is the lowest in three surfaces. © 2000 American Institute of Physics.
