We report on the formation of a tellurium nanosheet with MoOx cap by thermal annealing ion-implanted 2H–MoTe2 multilayers. The presence crystal defects generated ion implantation at an energy 90 keV accelerates incorporation O atoms and surface desorption Te in defective MoTe2 during annealing, subsequently, is formed around bottom regions due to segregation. For angle-resolved Raman spectrosco...

In this study, the adsorption and absorption behavior of porphyrin derivatives on inorganic nanosheets were investigated. The relationship between orientation angle (θad) maximum wavelength (λmax) tetra (N-methyl-4-pyridinium)-porphyrin (p-TMPyP4+) adsorbed clay nanosheet (Sumecton SA (SSA)) titania (TNS, Ti0.89□0.11O2−0.11) monolayer film prepared by Langmuir-Blodgett method was examined dichr...

Abstract The photocatalytic reduction of CO 2 is a promising strategy to generate chemical fuels. However, this reaction usually suffers from low photoactivity because insufficient light absorption and rapid charge recombination. Defect engineering has become an effective approach improve the activity. Herein, ultra-thin (~ 4.1 nm) carbon-doped Bi WO 6 nanosheets were prepared via hydrothermal ...

We report on the transport study of a double quantum dot (DQD) device made from freestanding, single crystalline InSb nanosheet. The freestanding nanosheet is grown by molecular beam epitaxy and DQD defined top gate technique. Through measurements, we demonstrate how (QD) can be in an tuning voltages applied to gates. also measure charge stability diagrams show that states inter-dot coupling be...

Ultrathin two-dimensional (2D) porous nanosheets are one of the most promising nanomaterials in various applications, whereas their synthesis is still challenging. Herein, ultrathin 2D amorphous TiO2 (a-TiO2) nanosheet aerogel synthesized via a surfactant-free assembly process followed by low-temperature calcination. The co-existing O—O and —OH groups on surface precursor break 3D spherical sym...

The integration of catalyst metals into the graphene-based composites can be a new way to ensure thermal and electronic conductivities of the catalyst support materials in polymer electrolyte membrane fuel cells. In this work, graphene nanosheets were synthesized via a mild and safer chemical route including three major steps: graphite oxidation, ultrasonic treatment and chemical reduction. The...

Nickel oxide has been widely used in chemical sensing applications, because it has an excellent p-type semiconducting property with high chemical stability. Here, we present a novel technique of fabricating three-dimensional porous nitrogen-doped nickel oxide nanosheets as a highly sensitive NO₂ sensor. The elaborate nanostructure was prepared by a simple and effective hydrothermal synthesis me...
