Graphene-based Bolometers

摘要: This article reviews recent research for development of sensitive graphene photon detectors in the infrared/far infrared/THz range. For this range, has promising potential thermal detectors. Graphene ultra-small volume and low electron density, which gives relatively large heating per absorbed fast response. At temperatures electron-phonon energy loss is small, so ultrasensitive power detection possible. We review on science base such detectors, outline major design challenges. Important factors that must be considered making useful include readout coupling efficiency, method temperature readout, isolation hot electrons.
