摘要：

Vertically standing graphene sheets (VSGs) were successfully grown on indium tin oxide (ITO) glass through plasma enhanced chemical vapor deposition system. The lateral size of the graphene sheets was evidently affected by the growth temperature. The VSGs with smaller sheet size were obtained at 600 degrees C thanat 500 degrees C. The dependence of the field-emission behavior of VSGs grown on ITO glass (VSGs/ITO) on the sheet size was investigated. The VSGs/ITO films with smaller sheet size possessed a higher field-enhancement factor and a lower turn-on field, which was proposed to be attributed to more field-emission sites and better electrical conductivity.
