Effect of the dot size distribution on quantum dot infrared photoresponse and temperature-dependent dark current

Effect of the dot size distribution on quantum dot infrared photoresponse and temperature-dependent dark current

The fit allows us to find the standard deviation and the average activation energy for electrons in the dot distribution, which is consistent with the peak energy of the photocurrent spectrum measured in the middle infrared. On the contrary, the activation energy found from a conventional Arrhenius...

description The fit allows us to find the standard deviation and the average activation energy for electrons in the dot distribution, which is consistent with the peak energy of the photocurrent spectrum measured in the middle infrared. On the contrary, the activation energy found from a conventional Arrhenius fit is well below the photocurrent peak energy.
