2. 1. Self-Switching Diodes for Zero-Bias Terahertz Detection

   Author : Andreas Westlund; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; self-switching diode; noise-equivalent power; SSD; graphene; zero-bias; InAs; InGaAs; terahertz; detector;

   Abstract : The self-switching diode (SSD) has been investigated as a potential terahertz detector in recent years. The SSD accomplishes a non-linear current-voltage relation through a field-effect, which enables detection at zero bias from microwave up to terahertz frequencies. In this work, SSDs were realised in two new materials; InAs and graphene. READ MORE

4. 2. Novel Terahertz Emitters and Detectors: InGaAs Slot Diodes and InAs Self-Switching Diodes

   Author : Andreas Westlund; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; InAs; InGaAs; slot diode; self-switching diode; zero-bias diode;

   Abstract : Two novel types of diodes for emission and detection of THz radiation have been investigated. The diodes are based on high electron mobility III-V heterostructures. Both diodes are aimed for room-temperature operation, for which there is a demand for new THz technology. For emission, slot diodes based on an InGaAs heterostructure were studied. READ MORE
