Electronic properties and circuit applications of networks of electrochemically exfoliated 2D nanosheets.

ABSTRACT: High aspect-ratio 2D materials are promising for solution-processed electronics, yet the factors controlling exfoliation remain unclear and relatively few solution-processed networks have been electrically characterized. Here we combine theory and experiment to show that electrochemical exfoliation of layered crystals with sufficient stiffness-anisotropy (in-plane/out-of-plane Young's modulus ratio >1.7) yields high aspect-ratio nanosheets with intrinsic mobilities μ_NS = 20-75 cm²V⁻¹s⁻¹ across transition metal dichalcogenides and related alloys. Impedance spectroscopy indicates that solution-deposited networks can achieve junction-to-nanosheet resistance ratios (R_J/R_NS) as low as ~3, supporting theoretical predictions that μ_NS/μ_Net = R
