Abstract :
Characteristics of new sensitive microwave detectors with a symmetrical low-barrier structure metal-semiconductor-metal (MSM) are studied. Circuits for connection of detectors to microwave and low frequency registration tracts are discussed. Expressions for volt-watt sensitivity and noise equivalent power are obtained and comparisons with characteristics of zero-bias Schottky (Mott) detectors are performed. The characteristics of symmetric sensing elements are comparable and in some cases superior than the similar parameters of zero-bias detectors.
