杂质对二硫化钼场效应晶体管磁滞效应的影响
Effect of impurities on hysteresis of MoS2 field-effect transistors
摘要
Abstract
Molybdenum disulfide (MoS2) has promising characteristics as semiconductor devices,but the large hysteresis observed in transfer characteristic curves limites its application in field effect transistors (FETs).The electrical characteristic curves of supported and suspended devices with MoS2 films prepared by chemical vapor deposition method were measured at room temperature (20 ℃).The hysteresis appeares both in supported device and suspended device,but the hysteresis in supported device is more obvious than that of suspended device.The results suggest that,the adsorption of oxygen and water molecular on the surface of MoS2 plays a crucial role in leading to the hysteresis,since the adsorbed molecular can capture charge carriers from the conduction band of the MoS2 channel.关键词
