Indirect tail states formation by thermal-induced polar fluctuations in halide perovskites

Indirect tail states formation by thermal-induced polar fluctuations in halide perovskites

The weak effects induced by lattice disorder on the optoelectronic properties of halide perovskites still remain elusive. Here Wu et al. confirm the indirect transition tail states in perovskite crystals which explain their low photoluminescence quantum yield, dual emission peaks and difficulties in...
