The Einstein solid is made up of single-frequency quantum harmonic oscillators, ϵ = �?ω = h ν displaystyle epsilon =hbar omega =hnu It has been acknowledged that Raman scattering spectroscopy is a powerful tool to characterize SiC crystals non-destructively. We review recent sizeable developments in the usage of Raman scattering… https://x.com/hongyuxin20/status/1818170912933564627
