Abstract

Thin films of cobalt (about 20 nm) were deposited on a silicon ⟨100⟩ substrate. The deposition was carried out using the e-beam technique. The films were oxidized under two different conditions: in vacuum and in a quartz tube furnace. The elemental cobalt and the two oxidized samples were characterized by the technique of x-ray photoelectron spectroscopy. Magnesium Kα radiation (1253.6 eV) was used as the source of the x-ray excitation. The spectral data in the cobalt 2p, 2s, 3s, 3p, Auger LMM regions, oxygen 1s region, and carbon 1s regions were recorded under a high resolution mode. The sample oxidized in vacuum showed features distinct from that oxidized in the quartz tube furnace. The data will serve as a comparison for the cobalt oxides formed under different processing conditions.

用 X 射线光电子能谱研究钴的氧化作用

在硅⟨100⟩基底上沉积了钴薄膜（约 20 nm）。沉积采用电子束技术。薄膜在真空和石英管炉两种不同条件下进行氧化。通过 X 射线光电子能谱技术对元素钴和两种氧化样品进行了表征。镁 Kα 辐射（1253.6 eV）被用作 X 射线激发源。在高分辨率模式下记录了钴 2p、2s、3s、3p、奥格 LMM 区、氧 1s 区和碳 1s 区的光谱数据。在真空中氧化的样品与在石英管炉中氧化的样品显示出截然不同的特征。这些数据将用于比较在不同加工条件下形成的钴氧化物。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
