Abstract
A defect structure, consisting of very small roughly cylindrical zones, was found in as-grown GaAs during observation by transmission electron microscopy. The zones are one atomic plane thick and 10–20 Å in length, lying parallel to 〈110〉. The density of defects in all samples observed was uniform at approximately 1017 cm−3. By using the results of a calculation of the optical absorptivity attributable to these defects and by assuming intermediate metallic conductivity, excellent agreement between theoretical and observed absorptivity was obtained.This publication has 8 references indexed in Scilit:
