摘要：
We report on a photoelectron spectroscopy study of Al-dopants in 4H-SiC epitaxial layers. For silicon carbide (SiC) samples with an Al concentration of 10(20) cm(-3) we have been able to detect the Al2p photoemission signal. The Al2p signal is recorded through the oxide layer with a thickness of about 0.4 nm. We identify the emission signal of dopants and of small clusters. The latter become oxidized by diffusion of oxygen through the native oxide. (C) 2003 Elsevier B.V. All rights reserved.
