Two-dimensional (2D) nanomaterials constitute one of the most advanced research targets in materials science and engineering this century. Among various methods for synthesis 2D nanomaterials, including top-down exfoliation bottom-up crystal growth, chemical has been widely used to yield monolayers layered compounds, such as clay minerals, transition metal chalcogenides (TMDCs), oxides, long be...

Abstract The development of high-precision large-area optical coatings and devices comprising low-dimensional materials hinges on scalable solution-based manufacturability with control over exfoliation procedure-dependent effects. As such, it is critical to understand the influence technique-induced transition metal dichalcogenide (TMDC) properties that impact design, performance, integration a...

We demonstrate a method to induce tensile and compressive strain into two-dimensional transition metal dichalcogenide (TMDC) MoS2 via the deposition of stressed thin films encapsulate exfoliated flakes. With this technique we can directly engineer magnitude by changing deposited film stress, therefore allowing variable be applied on flake-to-flake level. These stressors are analogous SiNx based...

WS 2 is an emerging semiconductor with potential applications in next-generation device architecture owing to its excellent electrical and physical properties. However, the presence of inevitable surface contaminants oxide layers limits performance -based field-effect transistors (FETs); therefore, novel methods are required restore pristine surface. In this study, thickness a layer was adjuste...
