A Novel Measurement of The Density of State Analysis

It is very important for the development of materials to measure the ionization potential and the density of state (DOS), which indicates the electron condition. With conventional method (UPS^※1), a vacuum environment is required, which is difficult to operate and initially costs a lot.

Photoemission Yield Spectroscopy in Air, short for PYSA (AC series), made by Riken Keiki, can easily measure the ionization potential in air at very low cost, and calculate the DOS easily. Only with a short-time measurement can bring you excellent quality and efficient development, we recommend our AC series.
