The possibility of using AlSb as a potential material for high-energy photon detection is examined by comparing the mobilities of the free carriers, the energy gap, the atomic number, and the carrier recombination time for AlSb, CdTe, Si, and Ge. It is concluded that at room temperature AlSb should be an intrinsically better high-energy photon detector than the three other materials. Simulated detector spectra for AlSb and CdTe are compared for ambient temperature detector performance.
