Die Reaktionsrate eines InGaAs Terahertz Detektors in Fliegeform bei Zimmertemperatur mit gebrochener Symmetrie
Abstract
A bow-tie InGaAs with broken symmetry has been designed for terahertz detection at room temperature. An active part of the detector consists of a two-dimensional electron gas which is heated non-uniformly with incident radiation. Main detector performances are operation in a passive scheme, flat frequency response up to 1 THz, the voltage sensitivity of about 5 V/W, the noise equivalent power of roughly 10 nW/Hz(exp 1/2), and the response time less then 7 ns.
