Popis: | Amorphous hydrogenated carbon (a-C:H) has been extensively researched as an electronic material. In this study, a-C:H is implanted with boron ions at a dose of 2×1015 cm−2. It is observed that the current versus voltage shows a number of distinct conduction regimes. The likely mechanism is a combination of space charge and barrier effects. A uniform implant throughout the film results in symmetrical characteristics, whilst an implant through only the first half of the film results in switching only on one side, reinforcing the suggestion that the conduction mechanism is barrier controlled. |
