Semiconductor terahertz detectors and absorption enhancement using plasmons

As novel applications using terahertz radiation are developed, there is an increased demand for sensitive terahertz detectors. This has led to new approaches for enhancing the response of terahertz detectors. Results were recently reported on the terahertz response of a p-type AlGaAs/GaAs, n-type GaAs/AlGaAs, n-type GaN/AlGaN, and p-type GaSb/GaSb Interfacial Workfunction Internal Photoemission...

Plasmonic terahertz detectors for biodetection

A report is presented on the biodetection capabilities of plasmonic terahertz detectors. Large changes in the terahertz response of plasmonic detectors loaded with solutions of globulin-free bovine serum albumin, arginine and heparin were measured for concentrations that did affect the device transfer characteristics. The consistent change of the response characteristics with specimen type and ...

Future of Semiconductor Based Thermal Neutron Detectors

Thermal neutron detectors have seen only incremental improvements over the last decades. In this paper we overview the current technology of choice for thermal neutron detection – He tubes, which suffer from, moderate to poor fieldability, and low absolute efficiency. The need for improved neutron detection is evident due to this technology gap and the fact that neutrons are a highly specific i...
