Photon-assisted transport can be considered
Photon-assisted transport can be modeled by considering electromagnetic (EM) modes at specific energies.
<EMfield> <EMmode> <PhotonEnergy unit="mV">253.0</PhotonEnergy> </EMmode> </EMfield>
Note that in the current version (2020-11-16), only a single EM mode is supported at a time.
The electric field in this EM mode can be either imposed (detection mode) or calculated self-consistently (gain clamping).
The detection mode is relevant to study quantum cascade detectors and/or to study the role of photon-assisted transport.
The electric field can be set in the following way: <EMfield> <EMmode> <PhotonEnergy unit=“mV”>253.0</PhotonEnergy> <ElectricField unit=“V.m^-1”>1.0e6</ElectricField> </EMmode>
The gain feature calculates the linear response to an a.c. incoming field. In this case, the d.c. current is not modified. On the other hand, the photon-assisted transport is modeled through the use of a self-energy to describe the influence of absorption and stimulated emission on d.c. transport.
Gain clamping is relevant to
