Abstract

Measurements are reported, for 0.5 mm thick semi-insulating (S.I.) GaAs wafers, of the neutral EL2 distribution, the pattern of dislocations, and of MESFET electrical parameters - these devices built on the same wafers. These results indicate that the device properties are more affected by EL2 nonuniformity than by dislocation density pattern.
