    Novel system for picosecond photoemission spectroscopy (1988)
    [S.l.] : American Institute of Physics (AIP)

    Notes: This article describes a laser-based source and detection scheme for performing time-resolved photoemission studies of materials. The pulsed laser source produces intense picosecond pulses of coherent radiation that are nearly continuously tunable from the near infrared to photon energies up to 13 eV. To achieve high sensitivity, a novel multianode time-of-flight spectrometer has been built that generates an angularly resolved intensity versus kinetic energy spectrum with better than 100-meV resolution. The source and detector provide an opportunity to study the electronic dynamics of excited systems on a picosecond time scale.

    Notes: High-resolution x-ray and ultraviolet photoemission spectroscopies have been applied to study the initial formation of the Cr- and Cu-polyimide interfaces. A model for the growth modes of these two interfaces is proposed based on comparison of experimental results with trends derived from quantum-chemical calculations.

    Tunable photoemission with harmonics of subpicosecond lasers (1994)
    [S.l.] : American Institute of Physics (AIP)
    Review of Scientific Instruments 65 (1994), S. 1853-1857

    Topics: Physics , Electrical Engineering, Measurement and Control Technology
    Notes: Soft x-ray photons, generated by the interaction of intense 610 nm subpicosecond laser pulses with rare gases, are used to carry out tunable angle-resolved photoemission on a number of systems. When the intensity at the focus of the input radiation exceeds ∼1014 W/cm2 significant quantities of harmonic photons at odd multiples of the input 610 nm (2.04 eV) light are produced. To date, harmonics from the 5th (10.2 eV) to the 25th (51 eV) have been generated with fluxes sufficient for generating photoemission spectra. The experimental apparatus for harmonic generation and several experiments demonstrating the applications of this light are described.

    Hybrid organic–inorganic semiconductor-based light-emitting diodes (1997)
    [S.l.] : American Institute of Physics (AIP)

    Details
    ISSN: 1089-7550

    Topics: Physics
    Notes: We demonstrate that the ability of GaN-based light-emitting diodes to emit in the short-wavelength regime makes possible "hybrid" organic–inorganic semiconductor light-emitting diodes that consist of two parts: a GaN-based electroluminescent part and an organic thin-film-based fluorescent part that absorbs the electroluminescence and fluoresces at a longer wavelength resulting in color conversion. We also show that organic films with much improved surface smoothness may be obtained by deposition at reduced temperatures. © 1997 American Institute of Physics.

    Electronic structure and dynamics of thin Ge/GaAs(110) heterostructures (1990)

    Topics: Physics
    Notes: Using angle-resolved picosecond laser photoemission we have investigated both occupied and transiently excited empty states at the surface of Ge grown epitaxially on GaAs(110). We observe a normally unoccupied, Ge layer derived state whose separation from the valence-band maximum of the system is 700±50 meV at six monolayers Ge coverage. The evolution of the electronic structure is followed as a function of coverage and correlated with low-energy electron diffraction. The time dependence of the transiently occupied Ge signal is compared with that of the clean GaAs(110) surface and shows that electrons are 〈me;40p〉prevented from diffusing into the GaAs bulk by the conduction-band offset of 330±40 meV.

    Notes: The temporal evolution of Ga and Ca vacuum deposited onto thin films of tris (8-hydroxy quinoline) aluminum (Alq) was studied with valence and atomic core level photoelectron spectroscopy. It was found that Ga, which exhibits weak reactivity with the Alq diffused into the organic at room temperature. Conversely Ca, a significantly more reactive metal, shows strong interaction with the organic surface. Effects of the initial morphology of the deposited materials on diffusivity will be described. © 1997 American Institute of Physics.

    Notes: High resolution atomic core level spectroscopy is carried out on condensed matter systems using tunable harmonics generated by focusing light from an amplified 150 femtosecond dye laser system operating at 610 nm, into a pulsed source of Ar gas. We show core level spectra collected with the 15th (30.54 eV), 17th (34.61 eV), and 19th (38.68 eV) harmonics of the dye laser light. Each harmonic is separated by 4.07 eV and possesses a narrow energy bandwidth which can be used to generate high resolution core level spectra.

    Renormalization of the one-dimensional π-π* band gap on the Ge(111) 2×1 surface (1992)
    Woodbury, NY : American Institute of Physics (AIP)
    Applied Physics Letters 60 (1992), S. 2631-2633

    Topics: Physics
    Notes: Using angle resolved laser photoemission spectroscopy we have measured the transient narrowing of the surface state band gap on the cleaved Ge(111) 2×1 surface. The reconstruction of this surface results in the formation of one-dimensional π bonded chains of atoms which give rise to bonding and antibonding bands whose energy/wave vector dispersions are one-dimensional as well. Photoexcitation of this surface produces a transient π* population which, in turn, leads to an observed narrowing of the surface band gap. We have investigated this renormalization as a function of surface carrier density and laser excitation fluence.
