Abstract

Electrical performance and transport mechanisms in 2-D transition-metal dichalcogenide materials should be investigated under a range of electrical parameters for practical application. In this paper, partially depleted (PD) molybdenum disulfide (MoS2) transistors were fabricated with a thick flake mechanically exfoliated from bulk crystals, and their operating mechanism is discussed considering the gate-uncontrollable conduction channel, the maximum depletion width (Dmax), and the impact of series resistance (Rsd). In addition, the intrinsic mobility of a neutral bulk channel in PD-MoS2 transistors was extracted from the simply separated gate-controllable drain current with a depletion approximation.
