用原位红外光谱和非原位四探针法研究了电子束辐照C60薄膜的结构和电学性质。红外光谱结果表明，辐照后的薄膜既不是石墨也不是碳纳米管，而是花生状的C60聚合物。电流-电压曲线表明，该聚合物具有金属性质，其电阻率为7Ωcm，而固体C60的电阻率为10~8-10 14Ωcm。这表明C60分子在电子束纳米制造过程中应用的可能性和开发碳基纳米器件的巨大潜力。
The structural and electrical properties of an electron-beam (EB)-irradiated C60 film have been examined at room temperature, using in situ infrared (IR) spectroscopy and ex situ four-probe measurements. IR results show that the irradiated film is neither graphite nor carbon nanotube-like but a peanut-shaped C60 polymer. Current–voltage curve shows that the polymer exhibits a metallic property with a drastically reduced resistivity of 7 Ω cm in comparison with 108–1014 Ω cm for solid C60. This indicates the possibility of applying C60 molecules in EB nanofabrication processes and large potential for developing carbon-based nanodevices.
