WebMay 8, 1995 · Abstract. Si diffusion and impurity-induced layer intermixing from a buried impurity source have been studied by transmission electron microscopy and secondary ion mass spectroscopy of isolated, Si-doped GaAs layers in an undoped Al{sub 0.4}Ga{sub 0.6}As/GaAs superlattice and by photoluminescence measurements on Si-doped GaAs … WebMay 1, 2024 · The elements in group III are common as acceptor impurities. The elements in group III include aluminum (Al), boron (B), and gallium (Ga). An acceptor is a dopant which forms p-type regions when …
