Abstract
Iron redistribution in InP(Fe) annealed without encapsulant has been studied by using secondary ion mass spectrometry. In annealed crystals, thin surface Fe accumulation followed by Fe depletion appeared. It was clearly shown that the Fe redistribution results from a thermally stimulated Fe outdiffusion with a diffusion coefficient D=D0 exp(−E/kT); D0=2.5×10−4 cm2 s−1, E=1.7 eV at the temperature range from 700 to 900 °C.This publication has 13 references indexed in Scilit:
