WebThin and single MoS2 flakes are envisioned to contribute to the flexible nanoelectronics, particularly in sensing, optoelectronics and energy harvesting. Thus, it is important to study their stability and local surface reactivity. Their most straightforward surface reactions in this context pertain to thermally induced interactions with atmospheric oxygen. WebApr 5, 2024 · Grain boundaries are expected to modify the material characteristics, such as, for example, electrical transport, mechanical properties, magnetism, or optical response. 16-18 Van der Zande et al. found enhanced electron transport parallel to GBs and no marked effect for transport perpendicular to GBs. 14 On the other hand, Ly et al. 19 …

WebApr 1, 2024 · Rapid and Large-Area Visualization of Grain Boundaries in MoS2 on SiO2 Using Vapor Hydrofluoric Acid. This work shows a simple approach for an efficient large-area visualization of the grain boundaries in continuous chemical vapor-deposited films and domains of MoS2 that are grown on a silicon dioxide (SiO2) substrate. WebGrain boundaries and certain contaminations induced by the transfer process exist in the transferred monolayer MoS2shown in figure 1(b). The Raman spectra of the transferred monolayer MoS 2 are shown in figure 2(c). Two prominent peaks (∼386.6and ∼404.2cm−1) corresponding to the E 2g(in-plane vibration between two S with respect to Mo atom) and A oak frame house extensions

WebThe structural, electronic and magnetic properties of large area chemical vapor deposited monolayer MoS 2 rely significantly on the presence of grain boundaries (GBs) and defects. In this study, first-principles … WebJun 12, 2013 · A rich variety of point defects and dislocation cores, distinct from those present in graphene, were observed in MoS2. We discover that one-dimensional metallic wires can be created via two different types of 60° grain boundaries consisting of distinct 4-fold ring chains. A new type of edge reconstruction, representing a transition state ... WebNov 18, 2014 · Here we systematically characterize chemical vapor deposition grown MoS 2 by PL spectroscopy and mapping, and demonstrate non-uniform strain in single-crystalline monolayer MoS 2 and strain-induced band gap engineering.
