A method of fabricating a mixed ionic-electronic conductor (MIEC)-based radiation detector, comprising:
- forming a halide-treated surface on a MIEC crystal to increase the stability and resistance to degradation of the MIEC crystal under an applied bias, wherein the MIEC crystal is TlBr crystal, and the halide-treated surface is one of a TlBrF or TlBrCl surface.
