Molybdenum disulfide (MoS2) has recently gained tremendous research interest due to its distinctive properties. A comprehensive understanding of the performance of MoS2 across a complete range of pressures is significant from the perspective of practical application. While extensive research has been conducted to explore the potential of MoS2 under extremely high pressures, there is still a lack of deep insights into how it performs under vacuum to normal pressures. In this experimental study, we examine the electrical behavior of MoS2 as the pressure varies from vacuum pressure to standard atmospheric pressure in N2 and O2, respectively. The IV measurements show that higher pressures induce faster oxygen adsorption of MoS2. In addition, the investigation into the effect of humidity reveals that humidity has a greater influence on the electrical behavior of MoS2 than oxygen.

真空至常压下单层二硫化钼氧和湿度相关电行为研究

二硫化钼 (MoS 2 ) 由于其独特的特性,最近引起了极大的研究兴趣。从实际应用的角度来看,全面了解 MoS 2在整个压力范围内的性能具有重要意义。虽然已经进行了广泛的研究来探索 MoS 2在极高压力下的潜力,但仍然缺乏对其在真空至常压下的表现的深入了解。在该实验研究中,我们分别检查了压力从真空压力变化到 N 2和 O 2标准大气压时 MoS 2的电学行为。在-V测量表明更高的压力会导致更快的 MoS 2氧吸附。此外,对湿度影响的研究表明,与氧气相比,湿度对 MoS 2的电学行为的影响更大。
