主 题：Au/Ga2O3 Surface plasmon polariton Enhance Solar-blind photodetector
摘 要：Surface plasmon polariton(SPP) is electro-magnetic wave coupled to free electron oscillations near the surface of metal, and has been used to improve the photoelectric properties in many optoelectronic devices. In the present study, the Au nanoparticles(NPs)/β-GaOcomposite thin film was fabricated through depositing Au ultra-thin film on the β-GaOthin film followed by post-thermal treatment. Compared to bare β-GaOthin film, a significant absorption around 510 nm, which is attributed to SPP of Au NPs, was observed in the UV–vis spectrum of Au NPs/β-GaOcomposite thin film. The results showed that the photoresponse of Au NPs/GaOphotodetector illuminated under 254 nm +532 nm light was much higher than that illuminated under 254 nm light, indicating an enhancement of photoelectric property for the solar-blind photodetector based on β-GaOthin film.
