Etching is a method employed during the fabrication of semiconductors to chemically remove layers from the surface of the wafer substrate. Etching is a crucial process, and each wafer is subject to ...

Definition:Raman Spectroscopy is a sophisticated analytical technique used to observe vibrational, rotational, and other low-frequency modes in a system. This material characterization technique ...

Raman spectroscopy is an analytical technique that allows for the assessment of molecular structure and the identification of materials by examining the rotational and vibrational modes of molecules.

During light scattering, the majority of scattered light undergoes no change in frequency (or energy), in a process referred to as referred to as elastic or Rayleigh scattering. Raman spectroscopy ...
