Research Abstract

Understanding of electronic structure near the Fermi level of electronic devices under operation is important from the view point of both basic and applied sciences. However, it is quite difficult in the precise observation of the electronic structure under the device operation due to the presence of electrodes and applied electronic fields. In this research project, we have developed the operand electronic structure analysis system based on the soft X-ray emission spectroscopy.
