Three-Dimensional Simulation of Signal Generation in Wide-Bandgap Semiconductor Radiation Detectors

J. E. Toney[1]
[1]Pennsylvania State University Electro-Optics Center, Freeport, Pennsylvania, USA

We demonstrate the use of Comsol Multiphysics with Matlab to model signal generation in wide-bandgap semiconductor radiation detectors. A quasi-hemispherical detector design is compared with a simple, planar detector. Results show that the quasi-hemispherical design can simply and effectively compensate for the poor hole transport of most compound semiconductor materials.
