New Schottky-barrier diodes, with an epitaxial layer thickness of < 1000 Ã and doping 2.5Ã1016 cmÂ¿3, yield a mixer noise temperature of 98 K at 115 GHz. The diodes have a diameter of 1.8 Â¿m, and show repeatable performance. Measurements indicate negligible capacitance variation to at least +0.2 V. The noise temperature is competitive with values reported for Josephson and quasiparticle junctions.
