Abstract: We have studied the mechanism of energy relaxation and resistive state formation after absorption of a single photon for different wavelengths and materials of single photon detectors. Our results are in good agreement with the hot spot model.

Fedorov GE, Gaiduchenko IA, Golikov AD, Rybin MG, Obraztsova ED, Voronov BM, et al. Response of graphene based gated nanodevices exposed to THz radiation. In: EPJ Web of Conferences. Vol 103.; 2015. 10003 (1 to 2).
Abstract: In this work we report on the response of asymmetric graphene based devices to subterahertz and terahertz radiation. Our devices are made in a configuration of a field-effect transistor with conduction channel between the source and drain electrodes formed with a CVD-grown graphene. The radiation is coupled through a spiral antenna to source and top gate electrodes. Room temperature responsivity of our devices is close to the values that are attractive for commercial applications. Further optimization of the device configuration may result in appearance of novel terahertz radiation detectors.
