Dear Zamil,

The electron mobility can be estimated by means of the Takagi formula , in terms of the effective mass, whic you can derive from the energy band structure E(k) and other ab-initio-calculated parameters. For more details,

read this pdf

https://arxiv.org/pdf/1111.1953.pdf

Good luck

Md. Rayid Hasan Mojumder

What I did about this:

Observed the lowest point of CB and highest point of VB

From the respective K-point calculated the effective mass of electron and hole (Follow the Youtube video: https://www.youtube.com/watch?v=SdGIwzV-A-o)

Considering a trial time constant, tau (as close as for graphene) you may now calculate as electron mobility = (electron charge * tau)/(effective mass of an electron)

Hope this helps. Thanks. Md. Yasir Zamil
