Title: transmission at different temp
Post by: sayantanu on August 21, 2018, 13:06

Dear ATK users,
I have calculated electrical and phonon transmission of a system. How can I calculate transmissions at different temperatures from those spectrum???

Please see the manual pages for the two analysis objects:

Note that the transmission spectrum itself is not really temperature-dependent, unless you introduce phonon scattering. The current can however strongly depend on temperature via the Fermi factors in the expression for the current from transmission, and this can be adjusted afterwards to simulate hot carrier effects (thermionic emission).
