利用高分辨X射线光电子能谱(XPS)研究了Mg掺杂的InxAl 1-xN合金(x ≥ 0.4)表面费米能级钉扎位置的变化。对于富In合金,在x ≤ 0.7的合金成分下推断出从反转到空穴耗尽的转变。对于富铝合金,由于p型掺杂AlN和富铝合金的困难,导致绝缘样品,导致近似平带条件,表面空间电荷很少。(© 2009 WILEY‐VCH Verlag GmbH & Co. KGaA,魏因海姆)
High resolution X‐ray photoemission spectroscopy is utilised to determine the variation in surface Fermi level pinning position for Mg‐dopedc‐plane InxAl1–xN alloys withx≥ 0.4. For In‐rich alloys, a transition from inversion to hole depletion was inferred at an alloy composition ofx∼ 0.7. For Al‐rich alloys, insulating samples resulted due to the difficulty of p‐type doping AlN and Al‐rich alloys, resulting in approximately flat‐band conditions, with little surface space‐charge.
