Abstract
Methods, systems, and apparatus that filters noise within a signal collected by a detector assembly. The detector assembly includes a first semiconductor layer of a first type configured to receive a photon. The detector assembly includes a second semiconductor layer of a second type. The second semiconductor layer is formed above the first semiconductor layer. The first semiconductor layer and the second semiconductor layer are configured to collect a signal. The detector assembly includes an interface layer including an insulator portion for filtering noise. The interface layer is formed on the second semiconductor layer. The detector assembly includes a metal contact layer formed on the interface layer. The interface layer is configured to capacitively couple the first semiconductor layer and second semiconductor layer with the metal contact layer.
