| 摘 要： | 采用真空蒸镀方法，利用液体衬底在沉积过程中的线性扩散过程，在玻璃表面制备出斜率仅为10-5的楔形金薄膜逾渗系统，并用四引线方法测量了从该薄膜系统中得到的均匀无序金薄膜的导电特性.实验结果表明：和通常的平整薄膜逾渗系统相比，该薄膜系统呈现更为强烈的跳跃电导和隧道效应.关键词：带状薄膜跳跃电导隧道效应 |

| Abstract: | A gold thin film percolation system, deposited on glass surfaces by the vapor deposition method, has been fabricated. By using the expansive and movable properties of silicone oil drop, a characteristic wedge - shaped film system with a slope of ～ 10-5 naturally forms during deposition. The electrical conductivity of the band-like gold film, i.e., the uniform part with a fixed thickness, is measured with the four-probe method. It is found that hopping and tunneling effects of the films are stronger than those of the other films. |
| Keywords: | band-like films hopping conductivity tunneling effect |
