Popis: | In this study, a series of β-Ga2O3 films are prepared by using triethylgallium (TEGa) and nitrous oxide (N2O) as precursors to explore the effect of N2O/TEGa ratio on the characteristics of β-Ga2O3 films. A metal/semiconductor/metal (MSM)-type solar blind ultraviolet (UV) photodetector (PD) is fabricated using as-prepared β-Ga2O3 film. It is found that an increment of N2O/TEGa ratio tends to suppress the oxygen vacancies in β-Ga2O3 film so the device performance can be significantly improved. This work gives a deep insight into the impact of TEGa/N2O ratio for depositing β-Ga2O3 on the film quality, the surface morphology, the chemical composition and the device performance for UV PDs. |
