The main objective of this program is to gain an in-depth understanding of the thermodynamics, solid-state kinetics, and growth properties in the Ag-Ga-Se system so that we can reproducibly grow high optical quality crystals of AgGaSe2. This program began at stanford on August 20, 1986. During the first four-month reporting period, emphasis was devoted to three areas growth of 37 mm diameter crystals, increasing our growth capacity so that we can carry out more than one experiment at a time, and studies on the effects of heat treatment parameters on residual scattering centers and residual optical absorption.
