For instance, there is a change in lattice parameter of silicon crystal doped with boron atoms. How can estimate the lattice parameter of silicon crystal in this case?. Is there any formula for this estimation?
Thanks a lot!
Hi everyone!How can How can i explain the Raman spectra of carbon material when D peak exists, while 2D peak does not. Could there be a reverse case when in Raman spectra we observe the overtone...
