Model: AlphaSE
Manufacturer: Woolam
Area: MiNaLab Clean Room

Material Class:

 Transparent solids

Technology Description:

 Ellipsometry can probe the complex refractive index or dielectric function tensor, which gives access to fundamental physical parameters and is related to a variety of sample properties. It is commonly used to characterize film thickness for single layers or complex multilayer stacks ranging from a nanometers to several micrometers.
