Research abstract
TlBr is a promising gamma radiation semiconductor detector material primarily
due to its high Z component and high density. TlBr detectors, however, suffer from
polarization at room temperature and degrade rapidly under applied bias. Polarization is
associated with ionic conductivity in this material. This proposal is focused on
controlling the point, chemical, and crystalline defects in TlBr to minimize ionic
conduction, and thereby enable operation of this promising detector at room temperature.
