Equipment is provided to test the applicability of surface second               harmonic generation (SHG) to the study of surface diffusion.                    Diffusion of gallium, arsenic, and their alkyl and chloride compounds           on silicon will be studied.  The equipment includes a high-power                short- pulse laser, a monochromator, and a piezoelectric translator.            In SHG, the adsorption-sensitive yield of frequency-doubled laser               light is detected in reflection from the surface.  Because SHG has              good spatial resolution (ca. 0.5 micron), it is particularly suited             for measurements of surface diffusion, which plays a dominant role in           many film-deposition processes.
