Dephasing effect in photon-assisted resonant tunneling through quantum dots
Dephasing effect in photon-assisted resonant tunneling through quantum dots
We analyze dephasing in single and double quantum dot systems. The decoherence is introduced by the B\"uttiker model with current conserving fictitious voltage leads connected to the dots. By using the nonequilibrium Green function method, we investigate the dephasing effect on the tunneling current. It is shown that a finite …
