In this article, the photovoltaic effect in a quantum ballistic channel (QBC) with a non-uniform narrowed end was investigated, and the authors used a mode-matching technique to obtain the photocurrent.Abstract:
Photon-induced intersubband scattering in a quantum ballistic channel (QBC) is investigated. The authors calculations show that light absorption in QBC with a non-uniform narrowed end can lead to a photovoltaic effect. Using a mode-matching technique the photocurrent is obtained. The evaluated responsivity, detectivity and band width of the proposed photovoltaic detector are conducive to practical application.read more
