Compute Hall coefficient and Hall conductivity tensors
« on: October 16, 2024, 09:07 »
Hello everyone,

Is there any tutorial available to compute Hall coefficient and Hall conductivity tensors?

Please let me know.

Thank you

The Hall coefficients can optionally be calculated via the Mobility study object, see https://docs.quantumatk.com/manual/Types/Mobility/Mobility.html. It's turned off by default because it's rather time-consuming.

There is no specific tutorial on it, but fundamentally it's just another output of a mobility study.

Hi,

Thank you for your reply.

Can I calculate the up-up, down-down, up-down, and down-up components of Hall coefficients?

I don't think so, I think it squashes all contributions into a single number (well, tensor).
