Abstract

Reflection electron microscopy (REM) and reflection high energy electron diffraction (RHEED) were used in a UHV electron microscope to study the effects of various surface treatments on the topography and crystal structure of cleaved GaP(110) surfaces. Reported ion-milling and annealing cleaning treatments resulted in rough surface topography, and in good 1 × 1 RHEED patterns. Annealing at 800°C resulted in surface smoothing, but also led to dissociation of GaP with viscous flow of a Ga-rich molten phase on the surface. Regions on the surface which were not covered by the molten phase maintained the 1 × 1 reconstruction typical of the clean GaP(110) surface.
