Cycling 2D crystal growth The electronic and optical properties of two-dimensional (2D) transitional metal dichalcogenides such as MoS 2 WSe could be modulated by creating in-plane superlattices heterostructures from these materials. However, single layers materials are fragile often do not withstand the processing conditions needed during subsequent steps. Zhang et al. developed a reverse-flow reactor that avoids thermal degradation unwanted nucleation. They demonstrate several examples...
Recently, 2D materials exhibit great potential for humidity sensing applications due to the fact that almost all atoms are at surface. Therefore, quality of material surface becomes key point sensitive perception. This study reports an integrated, highly sensors array based on large-area, uniform single-layer molybdenum disulfide with ultraclean Device mobilities and on/off ratios decrease linearly relative varying from 0% 35%, leading a high sensitivity more than 104 . The reversible water...
2D semiconductors are promising channel materials for field-effect transistors (FETs) with potentially strong immunity to short-channel effects (SCEs). In this paper, a grain boundary widening technique is developed fabricate graphene electrodes contacting monolayer MoS2 . FETs lengths scaling down ≈4 nm can be realized reliably. These graphene-contacted ultrashort exhibit superior performances including the nearly Ohmic contacts and excellent SCEs. This work provides facile route toward...
Epitaxial growth of A-A and A-B stacking MoS2 on WS2 via a two-step chemical vapor deposition method is reported. These epitaxial heterostructures show an atomic clean interface strong interlayer coupling, as evidenced by systematic characterization. Low-frequency Raman breathing shear modes are observed in commensurate bilayers for the first time; these can serve persuasive fingerprints interfacial quality configurations.
Abstract Two‐dimensional materials with intrinsic magnetism have recently drawn intense interest for both the fundamental studies and potential technological applications. However, to date been largely limited mechanically exfoliated materials. Herein, an atmospheric pressure chemical vapor deposition route ultrathin group VB metal telluride MTe 2 (M = V, Nb, Ta) nanoplates thickness as thin 3 nm is reported. It shown that resulting can be systematically evolved from mostly thicker hexagonal...
In this Letter, we report the observation of thermally induced rotation graphene on hexagonal boron nitride (h-BN). After rotation, two stable configurations h-BN with a relative lattice twisting angle 0° (most stable) and 30° (metastable), respectively, were found. Graphene below (above) critical ∼12±2° tends to rotate towards (30°) at temperature >100 °C, which is in line our theoretical simulations. addition, by manipulating annealing flake sizes graphene, moiré superlattices large...

We show that PtTe2 can be readily grown, using chemical vapor...
The depth-dependent defect manipulation strategy using binary modulators with selective penetrability within perovskite films can concurrently passivate the defects both in bulk and at interfaces, boosting efficiency of solar cell to 24.36%.
Among the key components of a smart grid, advanced metering infrastructure (AMI) has become preferred target for network intrusion due to its bidirectional communication and Internet connection. Intrusion detection systems (IDSs) can monitor abnormal information in AMI network, so they are an important means by which solve intrusion. However, existing methods exhibit poor ability detect intrusions AMI, because cannot comprehensively consider temporal global characteristics information. To...
Perovskite light-emitting diodes (PeLEDs) are the next promising display technologies because of their high color purity and wide gamut, while two classical emitter forms, i.e., polycrystalline domains quantum dots, encountering bottlenecks. Weak carrier confinement large leads to inadequate radiative recombination, surface ligands on dots main annihilation sites for injected carriers. Here, pinpointing these issues, we screened out an amphoteric agent, namely, 2-(2-aminobenzoyl)benzoic acid...
Control of the precise lattice alignment monolayer molybdenum disulfide (MoS 2 ) on hexagonal boron nitride (h‐BN) is important for both fundamental and applied studies this heterostructure but remains elusive. The growth precisely aligned MoS domains basal plane h‐BN by a low‐pressure chemical vapor deposition technique reported. Only relative rotation angles 0° or 60° between are present. Domains with same orientation stitch form single‐crystal, different orientations from mirror grain...
Monolayer transition metal dichalcogenides (TMDs) have attracted considerable attention as atomically thin semiconductors for the ultimate transistor scaling. For practical applications in integrated electronics, large monolayer single crystals are essential ensuring consistent electronic properties and high device yield. The TMDs available today generally obtained by mechanical exfoliation or chemical vapor deposition (CVD) growth, but often of mixed layer thickness, limited crystal domain...
