Fine structure in the spectra of thermalized photoelectrons emitted from GaAs with a negative electron affinity
Terekhov A. S., Orlov D. A.
Spectra of photoelectrons emitted from the Γ valley of GaAs with a negative electron affinity have been measured at 77 К with a resolution of 5 meV. These are the first such measurements. A fine structure which is seen in the spectra stems from particular features of the emission processes and of the thermalization of photoelectrons near the surface.
