Abstract: A structure having a semiconductor material film formed graphene material layer that is disposed on a substrate is provided. The structure consists of a heterostructure comprising a semiconductor material film, a substrate, and a graphene material layer consisting of one or more sheets of graphene situated between the semiconductor material film and the substrate. The structure also can further include a graphene interface transition layer at the semiconductor material film interface with the graphene material layer and/or a substrate transition layer at the graphene material layer interface with the substrate.

Abstract: An apparatus and method for operating a direct wafer bonded semiconductor radiation detector includes bonding a plurality of wafers, receiving a radiation signal from a radiation source thereby producing electron and hole pairs via the radiation signal interacting with the detecting device. A voltage source produces a voltage across the direct bonded wafers, thereby drifting the electrons and holes through the plurality of bonded layers. The drifted electrons and/or holes include total drifted charge information of the detector and are collected and processed either at the detector or remote from the detector.
