Description

1. Technical field

[0001] The invention belongs to the field of optics, in particular to a low-temperature polarized electron Raman scattering device. 2. Background technology

[0002] Raman scattering is a common phenomenon of inelastic light scattering. When a beam of light hits the sample, part of it is reflected, and the other part is refracted into the sample. This part of the light entering the sample can interact with various excitation processes in the material. After the interaction, the photons transfer momentum and energy to the sample. The internal excitation produces scattered light emission. In this way, the scattered light carries rich information about the various excitations inside the material. By detecting the scattering spectrum, the intrinsic fundamental properties of the material can be studied in depth. The scattering process here is Raman scattering.

[0003] Raman scattering technology has been widely used in modern scientific research and indust...
