Work during this quarter centered on the surface properties of GaInAs100 most of the measurements were made on samples containing 40 In and 63 In. In general the LEED-Auger behavior is the same as that found for GaAs. The highest white light photoemissive efficiencies at room temperature are reported. Threshold measurements indicate that in neither case is negative electron affinity NEA achieved, although the photoemission shows that the vacuum level has been considerably lowered. The temperature dependence of the photoemission is discussed. The surprising preferential desorption of In from GaInAs, reported earlier by Auger measurements, has been confirmed by Quadrupole Mass Analysis of the desorption products as a function of temperature.
