Abstract

Abstract: By measuring the resistance in situ during the deposition of C₆₀ on ultrathin metal layers at UHV system, we find that the change of sample resistance is universal and it is very sensitive to the thickness of the precusor metal films and the characteristics of the employed metal materials. This sensitivity of resistance change in metal-C₆₀ multilayers (bilayers) may be related to the charge transfer of metal to C₆₀ and surface bonding effects, hence can be used as a newpossible approach to probe the interfacial interactions between C₆₀ and metals.

Key words: thin film, interfacial interaction, resistance measurement

摘要： 通过在超薄金属层上蒸镀C₆₀时的电阻原位测量，我们发现在平均厚度约一个C₆₀单层范围内样品电阻有明显可观测的变化，电阻变化的方向和幅度与金属层厚度以及金属材料的种类有关。这一新的现象揭示出有可能利用宏观物理性质测量来间接研究C₆₀-金属界面相互作用，从而对常规微观谱测量的结果给出旁证和补充。
