Open Access research with a real impact on health...

The Strathprints institutional repository is a digital archive of University of Strathclyde's Open Access research outputs. Strathprints provides access to thousands of Open Access research papers by Strathclyde researchers, including by researchers from the Physical Activity for Health Group based within the School of Psychological Sciences & Health. Research here seeks to better understand how and why physical activity improves health, gain a better understanding of the amount, intensity, and type of physical activity needed for health benefits, and evaluate the effect of interventions to promote physical activity.

Abstract

Fabrication routes to realising ‘3D’ detectors in gallium arsenide have been investigated and their electrical characteristics measured. The geometry of the detector is hexagonal with a central anode surrounded by six cathode contacts. This geometry gives a uniform electric field with the maximum drift and depletion distance set by electrode spacings rather than detector thickness. The advantages of this structure include short collection distances, fast collection times and low depletion voltages depending on the electrode diameter and pitch chosen. These characteristics are fundamental for the application of 3D detectors in, for example, medical imaging and protein crystallography.
