发帖数: 61 | 1 Based on some literatures, the Raman peak width is related to crystal
structure. But what is the theory basis for this? any body have any ideas
about this? thank you very much.
If you know some big niu guy, please let me know .
Thanks | v*****s

time of the vibrational excited state. So my guess is that the crystal
structure will affect the coupling between neighbor molecules and thus
change the life time.

加越大的bias，或者heat更高的温度，FWHM就越宽，
如果你要的话我可以帮你找找那片paper |
