Description
The effects of 35-KeV electron beam and 60Co gamma radiation on modulation-doped GaAs-Al/sub x/Ga/sub 1-x/As heterostructures were studied by measuring the transport and the quantum transport of and the field effect on, the two-dimensional (2D) electrons in GaAs at the heterojunction interface. While the γ radiation in doses up to 1.3 x 106 rad causes no appreciable changes in the 2D transport properties, the electron beam irradiation reduces the electron mobility. This reduction in electron mobility is approx.50% for electron doses of 10-10 C/μm2
