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

Popis výsledku v původním jazyce

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&apos;s modulus ratio &gt;1.7) yields high aspect-ratio nanosheets with intrinsic mobilities mu(NS) = 20-75 cm(2)V(-1)s(-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 similar to 3, supporting theoretical predictions that mu(NS)/mu(Net) = R-J/R-NS + 1 and suggesting that further reductions in R-J will increase mu(Net) toward the nanosheet limit (mu(NS)). These networks display n-type, p-type, and ambipolar behaviour, with on/off ratios up to 10(5) and mobilities mu(Net) = 13 cm(2)V(-1)s(-1). Here, we show that such high-performing 2D materials enable functional solution-processed circuits, including inverters, buffers, a 4-bit digital-to-analog converter, and a circuit capable of encoding and decoding 7-bit ASCII messages.
