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.

We present a procedure to obtain reliable EM responses for a SIW interconnect with microstrip line transitions. The procedure focuses on two COMSOL® configuration settings: meshing size and simulation bounding box. Once both are properly configured, the implemented structure is tested by perturbing the simulation bounding box to ensure it has no effect on the EM responses.
