Lithium-ion electrolytic substrates for sub-1V high-performance transition metal dichalcogenide transistors and amplifiers

Abstract

Electrostatic gating of 2D transistors with ionic liquids presents intrinsic limitations. Here, the authors demonstrate n-type MoS2 and p-type WSe2 transistors on a lithium-ion solid electrolyte substrate, displaying sub-threshold values approaching the ideal limit of 60 mV/dec and complementary amplifier gain of 34 with 1 V supply.
