please help me. i really need a quick reply.
I study the bandStructure of SrS with and without Spin-orbit but I have no enough information to explanation it.
the Sr has([kr] 4s2 4p6 5s2) and S has([Ne] 3s2 3p4) Structure. I attache the bandStructure of this compound calculated using...
Perhaps i should clear more my question. Please guide me.
I calculate the optical properties of SrS compound.I have two question:
1. In the loss function, there are several picks. I want determine plasma frequensy. Does only the highest pick show position of plasma freqeuncy and other...
1- I calculate optical properties of a pure compound in framework of DFT with pseudopotential by software. I get several picks in loss function. Does only the highest , determine plasma frequency or all of them with different density of valence electrons?
2-can we conclude the...
In the textsbook i raed for frequencies that (real part of index refraction) |n|~1>>|K| (exitinction coefficient), we have transparent matter (weak absorbtion). If we have a bulk matter with big diameter, that there are no transmitted light ( i don't know it is possible or not), our matter...
I read in text for calculation dielectric constant in Lorentz model, we only regard electric field that coupled with each oscillator. So the magnetic field of input wave has no effect in calculation of dielectric constant in this model?
