| 英文摘要 | Improvement in the field emission properties of alpha-Fe2O3 nanoflakes is observed after high energy X-ray irradiation from synchrotron radiation. Field emission threshold field of alpha-Fe2O3 nanoflakes is found to decrease from 10.1 to 7.8 MV/m after X-ray irradiation with the dose of 9.0 x 10(14) phs/cm(2). Electrical measurement reveals that the potential barrier at the back contact between the alpha-Fe2O3 layer and the iron substrate changes after X-ray irradiation. The observed threshold field decrease is well explained by the changes in potential barrier at the back contact of alpha-Fe2O3 nanoflakes, which indicates the back contact plays an important role in controlling the field emission properties of alpha-Fe2O3 nanoflakes. Our study shows that the alpha-Fe2O3 nanoflakes are a promising material for the application as field emitter under X-ray environment. (C) 2013 AIP Publishing LLC. |
