✦ Synopsis

Nanoelectronic junctions were fabricated by electron beam lithography and wet etching of modulation doped GaAs /AlGaAs heterostructures. Voltage differences between the branches of the junctions lead to rectification characteristics, which persist up to room temperature. We have investigated the high frequency properties of the rectification. A microwave injected into one branch generates a direct current through the nanojunction.

A microwave photon counter can be based on upconversion of the microwave radiation to the optical domain, followed by the optical photon counting. The former process sets the detection bandwidth, the latter sets the time resolution sufficient for sub-THz photon counting at room temperature. We repor
