Neat monolayer tiling of molecularly thin two-dimensional materials in 1 min

Abstract

A new technique has been developed to easily and rapidly arrange molecularly thin 2D materials edge by edge on various substrates.

Nonvolatile Memories Based on Graphene and Related 2D Materials

“…Moreover, the possibility of having a large class of solution‐processed 2D materials enables their integration with polymeric materials or deposition/coating on different substrates. In this context, progress on large‐scale placement of 2D materials–based inks by the various deposition/coating techniques such as Langmuir–Blodgett, spin‐, spray‐ and rod‐coating, and inkjet printing, is enabling printing of 2D materials–based films and heterostructures on a large scale . Nonetheless, apart from the uniformity of large‐area films, the roughness of the deposited film is still an issue for both optical and electronic properties of the deposited films and worse than those obtained by micromechanical cleavage or the direct growth.…”

2D Superlattices for Efficient Energy Storage and Conversion

“…Recently, the spin‐coating process of various nanosheets dispersed in dimethyl sulfoxide (DMSO) was reported. A range of oxide nanosheets including Ti 0.87 O 2 , Ca 2 Nb 3 O 10 , graphene oxide (GO), and reduced graphene oxide (rGO) in varied lateral sizes (submicrometer to tens of micrometers) were neatly tiled into monolayers on different substrates within a few minutes . A multilayer superlattice film was fabricated through repeating the sequential spin‐coating processes (Figure c).…”

Recent progress on exploring exceptionally high and anisotropic H+/OH− ion conduction in two-dimensional materials

“…To achieve this, two possible strategies are proposed here, both of which involve the fabrication of large-area lamellar membranes composed of overlapped and stacked 2D nanosheets through the well-established liquid-based membrane formation techniques ( e.g. vacuum-filtration, 57 , 58 drop-casting, 59 , 60 spin-coating, 61 , 62 dip-coating, 63 spraying, 64 layer-by-layer electrostatic assembly 65 , 66 and Langmuir–Blodgett 67 , 68 ), followed by exposing the fresh in-plane conduction channels through properly scrolling or stacking.…”
