用高分辨X射线光电子能谱研究了InN光电子能谱中的芯能级线型。In 3d和N 1 s核心能级是不对称的，显示出高结合能的尾部，这归因于InN表面处存在的累积层中的导带等离子体激元的非弹性损失和/或屏蔽。非对称尾部的范围随着表面费米能级位置的降低而减小，这与累积层中较低的电子密度相关。(C)2008 Elsevier B. V.保留所有权利。
The core-level lineshape in photoemission spectra of InN is studied by high-resolution X-ray photoemission spectroscopy. The In 3d and N 1s core-levels are asymmetric, displaying a high binding energy tail which is attributed to inelastic losses to and/or screening by conduction band plasmons in the accumulation layer present at InN surfaces. The extent of the asymmetric tail decreases with decreasing surface Fermi level position associated with a lower density of electrons in the accumulation layer. (C) 2008 Elsevier B.V.
