Title: i have a question
Post by: Andre36 on July 2, 2019, 12:59

Hi
In the "https://docs.quantumwise.com/tutorials/mobility/mobility.html" tutorial, I can see that the reference material is graphene with isotropic energy bands (in all directions) near the Dirac point ( symmetrical point K). Therefore, it did not consider orientation in mobile computing. I was curious whether mobility could be calculated depending on the direction of anisotropic energy bands. Please let me know what changes needed to have in order to incorporate a specific direction (or general angle dependency)?
Thanks in advance
Andre

The mobility is actually computed as a tensor quantity, i.e., accounting for crystal structure anisotropy, see the manual and usage example at https://docs.quantumatk.com/manual/Types/Mobility/Mobility.html.
