Title: About the photocurrent calculated by QuantumATK
Post by: zhangguangping on July 27, 2021, 17:47
Dear ATK developers:

In the past days, I have looked into the photocurrent module in QuantumATK. As I understand,
(1) the photocurrent obtained by the photocurrent module is only the current induced by the photo illumination and it does not include that induced by the voltage between the source and drain.
(2) the transmission obtained from photonMediatedTransmission function is also the transmission induced by the photo illumination because I find the transmission is always zero for photon_energy = 0.0 eV.

Am I right?

(3) However, when I integrate the transmission obtained from photonMediatedTransmission function, the result is very different from the one obtained by Photocurrent module (from Photocurrent Report). Can you give some hints?

With best regards,
