Abstract

We present a study on the transparent conducting characteristics of graphene-based films prepared by means of rapid chemical vapor deposition. The graphene films were grown on quartz slides with a CH4/Ar mixed gas under a constant flow at 950°C and then annealed at 1,000°C. It was found that the graphene films present excellent electrical conductivity with high transparency. The conductivity is up to 1,240 S/cm, the sheet resistance is lower than 1 kΩ/sq, and the transparency is well over 85% in the visible wavelength range of 400 to 800 nm, showing that the graphene films have very low resistivity and superior transparency and completely satisfy the need for transparent conductors. These properties can be used in many applications, such as transparent conductor films for touch panels. PACS: 61.48.+c, 78.67.Pt, 68.37.Hk, 68.65.Ac.

摘要

我们展示了一项关于通过快速化学气相沉积制备的基于石墨烯的薄膜的透明导电特性的研究。石墨烯薄膜在 950°C 下以恒定流速用 CH4/Ar 混合气体生长在石英片上,然后在 1000°C 下退火。结果发现,石墨烯薄膜具有优异的导电性和高透明度。电导率高达 1240 S/cm,方阻低于 1 kΩ/sq,在 400 到 800nm 的可见光波长范围内透明度超过 85%,表明石墨烯薄膜具有非常低的电阻率和优异的透明度,完全满足透明导体的需求。这些特性可用于许多应用,例如触摸面板的透明导体薄膜。
