This work is an overview of some recent results concerning the low temperatures operation, linearity, and circular polarization studies of nanometer scale field effect transistors for the detection of terahertz radiation. Also first results on graphene transistors are discussed. © (2013) COPYRIGHT Society of Photo-Optical Instrumentation Engineers (SPIE).
