An excited surface state on GaAs(110) has been investigated using a technique which populates the state with a laser pulse and measures its properties by time-resolved photoelectron spectroscopy using synchrotron radiation. Measurements of momentum,

Cleaved GaAs surfaces decompose under weak pulsed-laser irradiation, leading to the formation of metallic Ga islands. The reduction of band bending nonuniformities in photoemission spectra acquired during the laser pulses, in concert with new core-le

Microphysics of Surfaces: Beam-Induced Processes.
In the course of investigations of electronic processes on laser excited semiconductor surfaces cleaved in ultrahigh vacuum, we have discovered the accumulation of Ga islands on GaAs (110) induced by laser pulse fluences far below those previously re

The pulsed-laser induced photochemical production of metallic Ga islands on the surface of GaAs cleaved, irradiated, and studied in ultrahigh vacuum (UHV) is documented through photoelectron spectroscopy and subsequent scanning electron microscopy. G

Nanosecond pump–probe photoelectron spectroscopy by means of synchrotron radiation from 6 to 130 eV anticipates the application of new short-wavelength sources with comparable photon energies but shorter pulse durations. The influence of pulsed-UV

Reflectivity, fluorescence and photoelectron spectra from CaF2 single crystals have been measured using synchrotron radiation in the 10 to 100 eV range. The spectra contain features ascribed to excitons and to the band structure. Peaks due to conduct

The excitation spectra for intrinsic luminescence due to recombination of self-trapped excitons at liquid helium temperature have been measured in NaCl, NaBr, RbCl and RbBr. The observed sequence of thresholds is explained in terms of multi-exciton p

By exploiting optical selection rules in a microwave-optical double-resonance experiment, it is shown that the fine-structure parameter D for the lowest triplet state of the self-trapped exciton changes sign from (+) to (-) along the sequence of crys
