Di: Amelia

One-pot synthesis of MoS2/WS2 ultrathin nanoflakes with vertically aligned structure on indium tin oxide as a photocathode for enhanced photo-assistant electrochemical hydrogen evolution reaction Thus, this uniquely developed highly nanocrystalline sputtered MoSe2 porous nanowall thin films with vertically aligned molecular layers deposited at room temperature is cost-effective and highly desirable for developing low-powered high-performance gas sensors. A cost-effective solution-based synthesis route to grow MoSe 2 thin films with vertically aligned atomic layers, thereby maximally exposing the edge sites on the film surface as well as enhancing charge transport to the electrode, is demonstrated for hydrogen evolution reaction. The surface morphologies of thin films are investigated by scanning electron microscopy and atomic force

Layered material MoS2 has been attracting much attention due to its excellent electronical properties and catalytic property. Here we report the synthesis of vertically standing MoS2 triangles on Abstract: In this work, we investigate the optimum temperature for the growth of few-layered vertical MoS 2 nanoflakes through single step Chemical vapor deposition (CVD). The synthesis was carried out at different temperatures keeping the precursor concentration, carrier gas flow, and the annealing time fixed. Few-layered MoS 2 with vertical morphology was formed at 650 Our CVD-grown multilayer MoSe2 thin-film transistors (TFTs) show p-type-dominant ambipolar behaviors, which are attributed to the formation of Se vacancies generated at the decomposition

In this communication, we present a synthesis process to grow MoS2 and MoSe2 thin films with vertically aligned layers, thereby maximally exposing the edges on the film surface. Such edge-terminated films are metastable structures of MoS2 and MoSe2, which may find applications in diverse catalytic reactions. For example, hollow microspheres with unique structural properties, such as high surface-to-volume ratio and superior light collection efficiency, arising from multiple reflections of light Cha Mauro Pasta within the interior void [13], and MoS 2 NSs with vertically aligned layers have shown outstanding photocatalytic performance [14]. The synthesis of two-dimensional (2D) layered materials with controllable thickness is of considerable interest for diverse applications. Here we report the first chemical vapor deposition growth of single- and few-layer MoSe2 nanosheets. By using Se and MoO3 as the chemical vapor supply, we demonstrate that highly crystalline MoSe2 can be directly grown on

Different from most studies of 2D materials with their atomic layers parallel to substrate, we have recently developed layer vertically aligned 2D material nanofilms. Built on these developments, here, we demonstrate the synthesis of vertical heterostructure of n-type MoS2 and p-type WSe2 with vertically aligned atomic layers. Our findings contribute to the comprehension of phase transition phenomena in MoS 2 thin films and further advancement in the synthesis techniques of MoS 2 thin films within wafer-scale deposition environments.
