Abstract

Electron Beam Electroreflectance (EBER), a low power-density form of cathodoreflectance, has been investigated for use in a wide variety of potential applications. Herein, we describe a phenomenological theory of EBER and provide experimental support for the inherent electroreflectance and thermoreflectance mechanisms. In addition to pair generation and heating proposed earlier, a new mechanism, electron charging of the surface, is identified from the 2f EBER signal of P-type semiconductors. Finally, we compare the potential advantages of EBER to those of photoreflectance.
