Abstract

Using undoped GaAs containing grain boundary, we performed annealing test to identify the processes occurring during heat treatment. We propose EL2 as a complex of double vacancy, AsGa and Asi. From the concentration change at grain boundary region we temporarily conclude that EL3 is a simple intrinsic defect.
