The Summer Undergraduate Research Fellowship (SURF) Symposium
The development of high-performance radiation detectors is essential for commercial, scientific, and security applications [1]. Due to the unique electronic properties of graphene (high-speed, low-noise), recent radiation detectors utilize graphene field effect transistors to sense charge carriers produced by radiation interactions in a gated semiconductor [2]. A study of the energy deposition due to the transport of gamma rays and electrons/positrons through typical elemental and compound semiconductors (Si, Ge, GaAs, and CdTe) will allow for a material optimization of these detectors. Geant4, a Monte Carlo based program that simulates the passage of particles through matter, was used to simulate Compton …
