CONDUCTIVITY AND HALL MOBILITY OF ION-IMPLANTED SILICON IN SEMI-INSULATING GALLIUM ARSENIDE

Abstract
Chromium‐doped semi‐insulating gallium arsenide has been successfully doped n‐type by ion implantation of silicon. Annealing studies are presented which show that at annealing temperatures in excess of 600°C, conductivity and Hall mobility rise to values comparable to those expected for heavily doped gallium arsenide.
