Coadsorption layers on a metal surface are models of catalytic and electrode reactions. In order to reveal the electronic structures of the surface coadsorption layers, it is necessary to create the coadsorption layers whose mixing ratios are systematically changed. In this study, we created the different mixing ratio coadsorption layers by using a laser induced thermal desorption method, and measured the electronic structures of the different coadsorption layers simultaneously by a position-sensitive electron energy analyzer. As a result, the X-ray absorption spectroscopy and resonant Auger electron spectroscopy is able to apply for the electronic structure measurements of surface coadsorption layers.

金属表面的共吸附层是催化反应和电极反应的模型。为了揭示表面共吸附层的电子结构，有必要建立混合比系统变化的共吸附层。在本研究中，我们利用激光诱导热解吸法制备了不同混合比的共吸附层，并用位置灵敏电子能量分析仪同时测量了不同共吸附层的电子结构。因此，X射线吸收光谱和共振俄歇电子能谱可以应用于表面共吸附层的电子结构测量。
