Abstract
Halide perovskites have garnered strong attention in R&D on ionizing-radiation detectors due to their tunable bandgap, efficient absorption coefficient, superior charge transport characteristics, versatile chemistry synthesis, and cost-effective manufacturing. Enhanced growth methods can yield perovskite materials with improved crystallinity, purity, and overall performance. In this work, we grew a series of lead-free halide perovskite materials, e.g., FA3Bi2I9 (FA=CH(NH2)2) and Cs3Bi2I9, using different growth techniques. Systematic microstructural-, electrical-, optical-, and mechanical- characterization results, together with radiation response testing, will be presented and discussed.
