利用飞秒激光直接还原工艺，成功地在石墨烯氧化物薄膜上按照预编程图形制作了石墨烯微电路。原子力显微镜(AFM)表征表明，由于氧的飞溅，XPS和X射线衍射技术证实了微图形的表面高度低于薄膜的其余部分。还原石墨烯的电阻率和电导率与飞秒激光的输出功率有很强的相关性。此外，石墨烯微电路的电流-电压曲线呈典型的线性关系，表明其具有稳定的电导。利用飞秒激光技术对石墨烯进行微纳米加工，可能会为石墨烯材料在电子微器件中的应用打开大门。(C)2010爱思唯尔有限公司。保留所有权利。
Graphene microcircuits have been successfully created on graphene oxide films via direct femtosecond laser reduction process according to preprogrammed patterns. Atomic force microscopy (AFM) characterization shows that surface height of the micropatterns was lower than the rest of the film due to the toss of oxygen confirmed by XPS and XRD techniques. The electric resistivity and conductivity of as-reduced graphene have strong dependences on output power of femtosecond laser. Moreover, current-voltage curves of graphene microcircuits show typical linear relationship, indicating the stable conductivities. The micro-nanoprocessing of graphene through femtosecond laser technologies might open the door for applications of graphene-based materials in electronic microdevices. (C) 2010 Elsevier Ltd.
