Graphene terahertz uncooled bolometers

WebMade available by U.S. Department of Energy Office of Scientific and Technical Information ... WebWe propose the concept of a terahertz (THz) uncooled bolometer based on n-type and p-type graphene layers (GLs), constituting the absorbing regions, connected by an array of undoped graphene nanoribbons (GNRs). The GLs absorb the THz radiation with the GNR array playing the role of the barrier region (resulting in nGL-GNR-pGL bolometer).
