a Schematic illustration of the LITT effect in a c-axis tilted film coated with AuNP layer. b HRTEM image of a BiCuSeO film grown on 20° miscut LaAlO3 (001) substrate. c–d SEM images of the AuNP layer with thickness of 4 and 7 nm, respectively. e HRTEM image of the sample of AuNP (7 nm)/BiCuSeO. f I–V curves between two indium electrodes on different samples. The inset is the variation of resistance of AuNPs/BiCuSeO samples with the AuNP layer thickness
