Abstract

A four point bending experiment was conducted to study the effect of stress on the electrical activation of implanted 29Si in GaAs. The stress distribution in the SiNx-coated GaAs was quantitatively examined. 29Si electrical activation was found to depend strongly on the magnitude of the stress when specimens were annealed under tensile stress; compressive stress had a negligible effect. The n-type GaAs was converted into p-type under excess tensile stress. This stress dependence of electrical activation is attributed to the differences in dislocation characteristics and its interaction with implanted Si under tensile or compressive bending.
