Abstract

Auger electron spectroscopy was used to determine the phase composition of Cr₂GeC MAX phase thin films. A distinctive feature of the formation of carbon-containing MAX phases is the shape of carbon Auger peaks, which is characteristic of metal carbides spectra. Features of the Auger spectra in the presence of secondary phases of chromium germanides are found. Their presence can manifest itself in an increase in the energy of the germanium peaks, which is caused by a chemical shift during the formation of the Cr–Ge bond. Moreover, we have detected the accumulation of electronic charge, which can be explained by the features of the surface morphology.

Cr2GeC 薄膜的欧杰电子能谱学

摘要利用欧杰电子能谱测定了 Cr2GeC MAX 相薄膜的相组成。含碳 MAX 相形成的一个显著特点是碳奥杰峰的形状，这是金属碳化物光谱的特征。我们还发现了铬锗化物次生相的奥杰光谱特征。它们的存在可表现为锗峰能量的增加，这是由形成铬-锗键时的化学位移引起的。此外，我们还检测到电子电荷的积累，这可以用表面形态的特征来解释。

期刊介绍： The Physics of Metals and Metallography (Fizika metallov i metallovedenie) was founded in 1955 by the USSR Academy of Sciences. Its scientific profile involves the theory of metals and metal alloys, their electrical and magnetic properties, as well as their structure, phase transformations, and principal mechanical properties. The journal also publishes scientific reviews and papers written by experts involved in fundamental, application, and technological studies. The annual volume of publications amounts to some 250 papers submitted from 100 leading national scientific institutions.
