- We developed a cryogenic graphene detector for the sub-THz range. Two types of detection operation are envisaged: the bolometeric and the photovoltaic. We find that the leading mode of operation is bolometric. The epitaxial graphene on SiC used in the detector has a strong temperature-dependent weak localization correction to the conductance below 25 K. The sub-THz radiation elevates the temperature of the electron system in the graphene, and thus suppresses the weak localization. No photovoltaic effect is detected. The responsivity of the detector reaches ∼1⋅10 A/W below 1 K.
