CuCrP2S6: A van der Waals material that defies conventional bulk photovoltaic effect (BPVE) theory

Caption

CuCrP2S6 transitions from a non-centrosymmetric structure at low temperature to a centrosymmetric average structure at room temperature but retains a zero-bias photocurrent along the polar a-axis, reaching approximately 1.5 times the magnitude observed in the low-temperature phase.
