Abstract

Inorganic double perovskite single crystals e.g. Cs2AgBiBr6 have great potential in detecting X- and Gamma-Radiation. These single crystals can be solution processed at low temperature and be possessing of low trap density, high charge carrier mobility, and a tunable bandgap. In this work, Cs2AgBiBr6 single crystals were synthesized using the solution growth method, and we tried to determine the potential of detecting X-Ray radiation by examining especially their electrical and optical properties. Besides that, the values determined by the IV measurement along the dominant {001} lattice plane (1.02x108 – 2.97x109 Ωcm) and the van der Paul measurements made along the trigonal upper surface and pseudo-hexagonal lower surface edges (2.88X109 – 4.39x1010 Ωcm) used for specifically demonstrate the correlation between structure and property. The density of trap states and charge-carrier mobilities, which were calculated from the IV characteristic curve measurements, are 4.44x109 – 6.79x1010 cm–3 and 0.07-24.4 cm2V–1s–1, respectively. Consequently, it has been seen that these crystals obtained by the solution growth method are suitable for use in radiation sensors applications.
