HBCU - ALLOYING AND DOPING EFFECTS ON RADIATION HARDENING PROPERTIES OF WIDE GAP SEMICONDUCTORS AND SCINTILLATOR CRYSTALS
Abstract
The goal of this project is to systematically investigate alloying and doping effects on radiation hardening properties of wide bandgap semiconductors and scintillator crystals. Radiation damage studies on some of these scintillators have been done, however, only select samples from undetermined crystal boule locations or doping concentrations were tested. Moreover, the lattice and radiation hardening effects of irradiation on these scintillators, as well as on the newly developed advanced semiconductor family, have not been examined, thus making it necessary for a more thorough, systematic research into these effects. The systematic investigation into the radiation tolerance of the proposed novel elpasolite scintillation and perovskite semiconductor compounds will benefit materials research in the development of detectors for nuclear and high-energy physics as well as space applications. Oil well logging, medical imaging, nuclear non-proliferation, nuclear treaty verification, safeguards, environmental monitoring, nuclear waste cleanup, border security, emergency response instruments, space physics and non-destructive testing are other applications that may benefit from the results of the study on the proposed scintillators and semiconductors.
