摘要对超高压条件下制备的Be表面，经热清洗、蒸发和氩离子轰击得到了俄歇光谱。从这些不同制备的表面得到的俄歇谱在dN(E)/dE与E谱中表现出不同的峰，这与能带结构的修饰有关。没有证据表明光谱上的差异是由表面杂质引起的。在清洁俄歇光谱上的氧化效应与其他人得到的结果一致。清洁Be表面的俄歇光谱温度变化与先前报道的x射线研究有关。
Abstract Auger spectra have been obtained from Be surfaces prepared under U.H.V. conditions, by thermal cleaning, evaporation and by argon ion bombardment. The resulting Auger spectra from these variously prepared surfaces exhibit different peaks in the dN(E)/dE versus E spectrum which relate to modifications in the band structure. No evidence is found that the difference in the spectra is due to surface impurities. Oxidation effects on the clean Auger spectrum are in agreement with those obtained by others. The temperature variation in the Auger spectrum from clean Be surfaces is discussed in relation to previously reported X-ray investigations.
