Metal-Barrier-Metal Junctions for Room Temperature Millimeter-Wave Mixing and Detection

In the past, metal-barrier-metal (MBM) point-contact diodes have been used at room temperature as coherent detectors from microwave to optical frequencies. For the first time, the millimeter-wave mixing and detection characteristics of stable thin-film Ni-NiO-Ni junctions fabricated by photolithographic means will be reported.
