|Title:||Stable field emission from layered MoS2 nanosheets in high vacuum and observation of 1/f noise|
|Abstract:||Field emission and current noise of hydrothermally synthesized MoS2 nanosheets are investigated in ultrahigh- vacuum and industrially suited high-vacuum conditions. The study reveals that the emission turn-on field is pressure dependent. Moreover, the MoS2 nanosheets exhibit more stable field-electron emission in highvacuum than in ultra-high-vacuum conditions. The investigations on field-emission current fluctuations show features of 1/f-type noise in ultra-high-vacuum and highvacuum conditions, attributed to adsorption and desorption processes. The post-field-emission results indicate the MoS2 nanosheets are a robust field emitter in highvacuum conditions. � 2015 The Author(s).|
