How to solve teh problem " Error in routine prtmob (1): The carrier density is 0"
I use the "dipole_sp" to calculate the transport of graphene, but i see the problem in epw2.out, i do not know how to solve it. =============== Temp Fermi Elec density Population SR Drift Elec mobility [K] [eV] [cm^-2] [e per cell] [cm^2/Vs] ==========================================================...

dielectric tensors in phonon calculation using the QE
Hello everyone, Using the QE, i obtain the dielectric tensors by ph.x, i want to know, Is this dielectric constant a high frequency dielectric constant or a static dielectric constant? thank you very much. <EPSILON type="real" size="9" columns="3"> 1.040587278179623E+002 7.105427357601002E-015 -7.10...

" matrix is singular" in 2D materials using EPW
Dear all.
i calculate the transport property of 2D material, but i encounter the problem " Error in routine inv_mat (1): matrix is singular " using epw.
how to deal with it? thanks.
