In the bolometric regime, electron and hole branches demonstrate a very different response to THz radiation, which we link to the asymmetry of the current-voltage characteristics temperature dependence with respect to the Dirac point. Obtained results are important for development of high-efficiency graphene THz detectors. %G English %2 https://hal.science/hal-00954517/document %2 https://hal.science/hal-00954517/file/Graphene-Plasmonic-APL-2013.pdf %L hal-00954517 %U https://hal.science/hal-00954517 %~ CNRS %~ L2C %~ MIPS %~ UNIV-MONTPELLIER %~ UM-2015-2021
