Strathclyde Open Access research that creates ripples...

The Strathprints institutional repository is a digital archive of University of Strathclyde's Open Access research outputs. Strathprints provides access to thousands of research papers by University of Strathclyde researchers, including by Strathclyde physicists involved in observing gravitational waves and black hole mergers as part of the Laser Interferometer Gravitational-Wave Observatory (LIGO) - but also other internationally significant research from the Department of Physics. Discover why Strathclyde's physics research is making ripples...

Strathprints also exposes world leading research from the Faculties of Science, Engineering, Humanities & Social Sciences, and from the Strathclyde Business School.

Abstract

The charge sharing present in a 55 micrometer square pixel matrix of 300 micrometer thick silicon is examined. This is achieved using a commercial simulation package to investigate the diffusion effects on the charge cloud of created electrons and holes. The total fraction of charge shared is found to be 20.8%, but this can be reduced by the addition of a minimum threshold level of detection. The optimum level giving all of the signal but with the minimum of noise is found to leave 10.4% charge shared on average.
