Is AMSET electronic thermal conductivity calculated under open or closed circuit conditions?

Hi everyone,

I’m using AMSET to calculate electronic thermal conductivity for my material, but I was wondering about the boundary conditions used in these calculations. Specifically, is the electronic thermal conductivity computed assuming open circuit or closed circuit conditions? How does AMSET handle this aspect of the calculation?

Any clarification would be greatly appreciated!

Thank you!

Hi lsj542261156,

The electrical thermal conductivity given by AMSET is the open circuit value.

To see how this was calculated, please refer to:

[1] Chapter 5 of Lundstrom, Mark S., and Changwook Jeong. Near-equilibrium transport: fundamentals and applications . Vol. 2. World Scientific Publishing Company, 2012.
