Negative elements in electron-phonon coupling matrix

Hi, I am trying to calculate deformation potentials for use in scattering rates for cubic silicon carbide and cubic boron nitride. To do this I am calculating the electron phonon coupling matrix following the method given here https://journals.aps.org/prb/abstract/10.1103/PhysRevB.104.19520 However ...

Electron-Phonon coupling matrix for conduction bands

Hi all, I am trying to calculate the electron-phonon coupling matrix elements for SiC at the conduction band minimum, however with "prtgkk = =.true." the ouptu file only contains the el-ph matrix elements for the 4 valence bands. I have been trying to extend the what is shown in Exercise 2 of Hands ...

Re: Electron phonon matrix element for all bands

Hi H. Lee, I know I'm not the original poster but I ham having a similar problem and couldn't find an answer. I am trying to calculate the electron-phonon coupling matrix elements for the first conduction band of SiC however I am only getting the coupling elements for the valence bands and I am not ...
