Photo-reflectance spectroscopy enhances semiconductor quality control with sensitive, contactless measurements of band structure and electric fields in devices.

Nonthermal and thermal plasmas are used in the industrial, engineering, medical, and research industries. Plasma composition is an important parameter in any plasma process. Using optical emission ...

“Plasma” refers to a gas with a significant proportion of ionized molecules, which produce various excited ions, atoms, and molecules. Electrons liberated from ions and atoms are highly energetic and ...

In a recently published 560-page book edited and co-authored by Kennedy College of Sciences Dean and Physics Prof. Noureddine Melikechi, researchers describe the way they are using light to identify ...
