Description
The J.A. Woolam M-2000 spectroscopic ellipsometer is a tool for optical thin film analysis that enables determination of thickness, optical constants n and k (refractive index and absorption coefficient), and allows modeling of electronic characteristics such as majority carrier concentration and band-gap. The beam incidence angle ranges from 45-90°, allowing both standard ellipsometry and transmission measurements. It is equipped with a motorized sample stage that enables wafer-scale measurements. The CompleteEASE control and analysis software possesses detailed measurement and modeling capability.
