利用原子力显微镜（AFM）研究了微二硫化钼（MoS2）的摩擦磨损行为，并对导电探针和基体施加正负偏压。实验结果表明，外加法向电场可以调节MoS2纳米片与AFM探针之间的纳米摩擦力.摩擦力随外加偏压的增大而增大。最大偏差具有阈值。当偏压超过阈值时，会促进MoS2电荷转移的形成，加速摩擦过程中的氧化。与无偏置条件下的摩擦力相比，摩擦力的调谐值可提高2倍。提出了一种可行的、有价值的调节MoS2体系摩擦特性的策略，对实际应用中理解和控制纳米摩擦具有重要意义。
The friction and wear behavior of micro-molybdenum disulfide (MoS2) is studied by atomic force microscope (AFM), and both positive and negative bias are applied to the conductive probe and substrate. The experimental results show that the nano-friction between MoS2nano-sheets and AFM probes can be regulated by an external normal electric field. Friction force will increase with the increase of the external bias. The maximum bias has a threshold value. If the bias exceeds the threshold, it will promote the formation of MoS2charge transfer and accelerate oxidation during the friction process. The tuning value of the friction force can be increased by 2 times, compared with the friction force under the condition of non-bias. We propose a feasible and valuable strategy to adjust the friction characteristics of the MoS2system, which provides great significance to understand and control the nano-friction in the practical application.
