摘要:

采用软X射线吸收谱研究了铁电电容器中Ti的L边。内光电流和X射线吸收光谱与偏振态有关。结果解释的光电效应和铁电电容器中的内部电位的基础上,作为一个结果的背靠背肖特基势垒叠加的电位由于退极化场。一般来说,所提出的方法提供了一个机会,以调查在薄膜器件中的掩埋金属-绝缘体和金属-半导体界面的电子结构。通讯作者:h.h. fz-juelich.de

英文摘要:

We applied soft X-ray absorption spectroscopy to study the Ti L-edge in ferroelectric capacitors using a modified total electron yield method. The inner photo currents and the X-ray absorption spectra were polarization state dependent. The results are explained on the basis of photo electric effects and the inner potential in the ferroelectric capacitors as a result of back-to-back Schottky barriers superimposed by the potential due to the depolarization field. In general, the presented method offers the opportunity to investigate the electronic structure of buried metal-insulator and metal-semiconductor interfaces in thin film devices.
