Thank you for your quick reply and apologize for my delay in responding.

I've already tried  E-dependent method but somehow the mobility matrix does not seem to be isotropic.

And, if the material is anisotropic, can I use the E-dependent method.

thanks

General Questions and Answers / 3D-material mobility

« on: November 15, 2018, 13:13 »

Hi,

I have already read the tutorial and accomplished calculating the mobility of graphene and some other 2D-materials. Recently my supervisor required me to calculate a 3D-material’s mobility and I was wondering if the electron-phonon-coupling calculation should contain k- and q-points on z-axis. If so, our computer can’t handle so many points.  Hence, how should I calculate 3D-material's mobility?

Besides, I also want to know how to judge if the k- and q-points are big and dense enough?

thanks
