Abstract
Radiation detectors include a radiation-sensitive semiconductor substrate and at least one asymmetric contact (i.e., a cathode electrode or anode electrode) that exhibits different blocking effect for charge carriers (i.e., holes and electrons) of opposite types. In one exemplary embodiment, a radiation detector includes a cathode electrode having a first metallic material having a work function that is ≥4.6 over a first surface of the radiation-sensitive semiconductor substrate, and at least one anode electrode including a second metallic material having a work function that is ≤4.6 over a second surface of the radiation-sensitive semiconductor substrate. In other embodiments, at least one of the cathode electrode and/or the anode electrode(s) include a metallic material and a semiconductor material layer between the metallic material and the surface of the radiation-sensitive semiconductor substrate.
