Mapping Semiconductor Bandgaps with Spectroscopic Ellipsometry

One of the most significant properties of semiconductors is their bandgap energy. A material's bandgap plays a critical role in determining the electrical conductivity, optical properties, and overall functionality in a wide array of devices. Our ellipsometry expert Dr. Max Junda describes how spectroscopic ellipsometry can be used to map the uniformity of and changes to bandgap energies as a result of material processing.
