Polarity-Reversed Robust Carrier Mobility in Monolayer MoS2 Nanoribbons

摘要: Using first-principles calculations and deformation potential theory, we investigate the intrinsic carrier mobility (μ) of monolayer MoS2 sheet nanoribbons. In contrast to dramatic deterioration μ in graphene upon forming nanoribbons, magnitude armchair nanoribbons is comparable its counterpart, albeit oscillating with ribbon width. Surprisingly, a room-temperature transport polarity reversal observed hole (h) electron (e) being 200.52 72.16 cm2 V–1 s–1 sheet, 49.72 190.89 V–1 s–1 4 nm nanoribbon. The high robust are attributable different characteristics edge states inherent Our study suggests that width reduction together engineering provide promising route for improving properties nanostructures.
