a LWF and fitting line at the interface of +P Au/BTO in the dark (black) and 355 nm UV light (red). In dark, φbi = 32.2 mV, L = 90.7 nm. In light, φbi = 78.5 mV, L0 = 52.3 nm. b LWF and fitting line at the interface of −P Au/BTO in the dark (black) and 355 nm UV light (red). In dark, φbi = 32.9 mV, L = 98.5 nm. In light, φbi = 85.6 mV, L0 = 55.1 nm. c Diagram of charge separation of Au/BTO at +P(left) and −P(right) in the dark (black solid line) and light (red dashed line).
