Hexagonal YMnO3 films as promising ultraviolet photodetectors
Source abstract
Abstract
Abstract Hexagonal rare-earth manganites (h-RMnO3, R = Sc, Y, Ho-Lu) exhibit intricate multiferroic properties and may be utilized for various technological applications ranging from non-volatile memories to solar cells and photo-detectors. Here, we report the epitaxial growth of hexagonal YMnO3 (h-YMO) films with different thicknesses deposited on yttria-stabilized zirconia (YSZ) substrates and their photoresponses to ultraviolet (UV) light. The structural characterizations illustrate that all the films present high quality epitaxy with out-of-plane h-YMO(0001)//YSZ(111) and in-plane h-YMO[12 3 0]//YSZ[110] relationship. Meanwhile, UV light driven photoresponses of these as-prepared films based on the planar photodetector structure with transparent Al-doped ZnO (AZO) as top electrodes are explored. It is revealed that the photocurrent will first increase and then decrease with increasing film thickness. The highest photoconductivity gain is ~387.4 observed at +4 V bias for the device with 160 nm YMO film. These results provide a guideline for hexagonal rare-earth manganites to work for UV photodetector application.
