Raman spectroscopy

Raman spectroscopy is used to learn about the characteristics of semiconductors. There are 2 types of semiconducting materials: intrinsic semiconductors, which are highly pure, and extrinsic semiconductors, which are mismatched materials. Raman spectroscopy is an effective instrument for analyzing semiconductor surfaces or contacts composed of a semiconductor and a metal or an insulator, as well as characterizing the stresses caused by heavy doping in semiconductors. Raman scattering from an extrinsic semiconductor, for example, can give rise to an adjustable light beam.

When light is incident with particles in a gas, liquid, or solid, the large proportion of particles are scattered or spread simultaneously energy as the incoming photons. This is characterized as Rayleigh scattering or elastic scattering.



Metals and alloys are not permitted. The Rayleigh effect is comparatively weak, leading to a lack sensitivity and difficult monitoring low amounts of a material. This can be reduced by applying one of the alternate strategies that boosts the effect.
