Shaping surfaces and interfaces of 2D materials on mica with intercalating water and ethanol

Interfaces between mica and graphene, as well the transition metal dichalcogenides (TMDCs) MoS2 WS2, were wetted with water ethanol, investigated employing scanning force microscopy molecular dynamics (MD) simulations. Below 25% RH, wets graphene-mica interface labyrinthine structures, exhibiting branch widths of about 50 nm for single layers increasing to almost an order magnitude more four graphene layers. At mica-TMDC interfaces, films exhibit a from compact morphology upon going single- multi-layers TMDCs. Ethanol show at all regardless number 2D material on top. The film morphologies are attributed equilibrium electrostatic repulsion preferentially oriented dipoles, line tension areas, which is dominated by deformation materials edges wet areas. front wetting under multilayers TMDCs much larger bending stiffness these than multilayers. thickness dependent may be employed shape their surfaces nano- micrometer scale.
