Abstract

TUNNETT diodes are low-noise oscillators based on transit-time delay on tunneling injection of electrons. We have fabricated TUNNETTs and demonstrated sub-THz imaging using a continuous-wave (CW), fundamental-mode generator in the frequency up to 706 GHz. Some biomedical applications have been demonstrated using the feature of TUNNETT as predominant stability of the power. A scanning sub-THz imaging has been demonstrated for an inspection of tissues from internal organs containing cancer cells, and skin surfaces.
