Device modeling for split-off band detectors
An approach to develop room temperature detectors is to use transitions between the light/heavy hole bands and the split-off hole band to produce enhanced response at high temperature. Results are presented on a theoretical model to predict the response in these split-off detectors. The model calculates the dark and illuminated currents from the photoabsorption, carrier escape, and transport, e...
متن کاملA hematoma detector—a practical application of instrumental motion as signal in near infra-red imaging
In this paper we discuss results based on using instrumental motion as a signal rather than treating it as noise in Near Infra-Red (NIR) imaging. As a practical application to demonstrate this approach we show the design of a novel NIR hematoma detection device. The proposed device is based on a simplified single source configuration with a dual separation detector array and uses motion as a si...
متن کاملPerformance Improvements of a Centrifugal Pump with Different Impellers using Polymer Additive
In this study, the performance of a centrifugal pump is investigated by adding polyacrylamide (PAM) polymer over the working fluid which is tap water in this case. PAM is a long chain polymer that leads to reduce the wall shear stress and drag in a turbulent fluid. Three different blade profiles including radial, straight backward and circular backward have been examined. For this purpose, a ce...
متن کامل30TH INTERNATIONAL COSMIC RAY CONFERENCE Cloud Monitoring at HiRes Detector using Infra-Red Sensors
Monitoring of the atmospheric conditions is very important for fluorescence observations. Particularly, the presence of clouds can drastically distort the signal from the extensive air shower. Infra-red (IR) sensors, measuring sky temperature, can help to distinguish clouds, which are usually significantly warmer than clear skies. Array of such sensors, covering the detector’s field of view, wa...

A GaAs/AlGaAs heterojunction is used as a spin-split-off band IR detector operating at or around room temperature. This detector structure followed a similar layer architecture to the quantum well IR photo detect...
