Introduction
Raman spectroscopy has become a major measurement in the field of nanotechnology with its unique information, rich information, simple sample preparation, and no damage to the sample.
One of the characterization means. With the development of new materials such as fullerenes, graphene, and carbon nanotubes and high-tech industries such as MEMS and semiconductors,
As the requirements for the characterization and measurement of microstructures and stress effects continue to increase, so does the accuracy of Raman frequency shift measurements. such as
The Raman frequency shift is closely related to the structure of the material. Its minor changes, in addition to the qualitative nature of the material, can also reflect charge doping and deformation stress.
Therefore, the calibration of the Raman shift has significant implications for the development of Raman spectroscopy.
The development of this standard will provide methods for the calibration of Raman shifts using standard substances and the uncertainty introduced by the calibration process for Raman
The comparable and reliable basis for the frequency shift measurement results promotes the use and development of Raman spectroscopy in nanotechnology and other fields.

4 Overview
Raman spectroscopy is a molecular scattering spectrometer that produces modulated frequencies due to inelastic scattering when the material is exposed to monochromatic radiation energy.
The spectrum. The Raman frequency shift is closely related to the structure of the material. Its minor changes, in addition to the qualitative nature of the material, can also reflect the charge doping and shape.
The stress is changed, so the Raman shift needs to be calibrated. When Raman spectrometers are used, monocrystalline silicon is generally used for preliminary calibration to check the instrumentation.
state. When performing measurements, linear calibration of multiple Raman shifts across the entire raster range is required. At this point, the calibration of the Raman shift needs to be established
Curves, and find the linear correlation coefficient of the calibration curve. This standard provides comparable and reliable basis for Raman frequency shift measurement results and promotes Raman
The use and development of spectroscopy in nanotechnology and other fields.
