摘要：
A survey of metal (Pd, Ni, Au, Ag, Mg, Ti, and Al) Schottky barrier contact formation to p-type Si-face (0001) and C-face (0001BAR) 6H-SiC by using x-ray photoemission spectroscopy is reported. The Schottky barrier height phi(B) ranges from 1.17 to 2.56 eV and is influenced by the contact metal work function and the 6H-SiC crystal face. A comparison with prior phi(B) values for n-type material indicates that for SiMilarly prepared metal/6H-SiC interfaces (including those which have been annealed) phi(Bp) and phi(Bn) sum to the 6H-SiC band gap.
