Development of a Superconducting Low-Noise 3.1-THz Hot Electron Bolometer Receiver

We have developed a hot electron bolometer mixer (HEBM) at 3.1 THz with a terahertz quantum cascade laser (THz- QCL) as a local oscillator. Both the HEBM and the THz-QCL device are fabricated in our laboratory. NbN film with 3 nm thickness was deposited on MgO substrate. The output power of the meta...
