| 英文摘要 | epsilon-Ga2O3 films with and without Zn impurity were epitaxially grown by metal organic chemical vapor deposition on a c-plane sapphire substrate, and were then face-to-face annealed in an oxygen atmosphere at 600 degrees C. The structural and photoelectric properties of the thin films were characterized and analyzed in detail. The Zn-doped epsilon-Ga2O3 photodetector exhibits an ultra-high specific detectivity of 1.7 x 10(16) Jones, a very quick response speed of less than 40 ms, and an extremely high UV-visible rejection ratio of 2.0 x 10(8) at a 10 V bias. In addition, the temperature dependent photoresponse properties have been investigated from 30 degrees C to 190 degrees C. The compensation effect of Zn impurities and their suppression of oxygen vacancies, as well as the improvement of crystal quality, should be responsible for the excellent performance of the device. Our results provide a new idea and guidance for achieving high-performance solar-blind photodetectors based on Ga2O3. |
