The quality of as-synthesized monolayers plays a significant role in atomically thin semiconducting transition metal dichalcogenides (TMDCs) to determine the electronic and optical properties. For designing optoelectronic devices, exploring the effect of processing parameters on optical properties is a prerequisite. In this view, we present the inf...
Monolayer MoS2 has received special consideration owing to its intriguing properties and its potential to revolutionize modern technologies. Atmospheric pressure chemical vapor deposition (APCVD) is the traditional method to grow uniform and high-quality MoS2 flakes in a controlled manner. Little is known, however, about their synthesis mechanism a...
We report the superconducting properties of the tungsten (W) nanowires fabricated using focussed ion beam (FIB) technique having different wire widths of ∼120 nm and ∼290 nm. The transport properties of these wires were measured down to a temperature of 20 mK in a dilution refrigerator. We observed hysteretic current- voltage characteristics (IVCs)...
To get insight into the thermal management of twisted bilayer graphene based devices, the interpretation of temperature variation on twisting properties becomes crucial. In this aspect, we report the temperature dependent Raman scattering of twisted bilayer graphene (tBLG) on the Si substrate having SiO2 thickness 300 nm. The tBLG samples have been...
An attempt has been made to understand the thermodynamic mechanism study of the low-pressure chemical vapor deposition (LPCVD) process during single-layer graphene (SLG) growth as it is the most debatable part of the CVD process. The intensive studies are being carried out worldwide to enhance the quality of LPCVD-grown graphene up to the level of...
A novel strategy has been devised to develop a single excitable dual emissive luminescent pigment for the formulation of unclonable security ink. This new advanced security features of the ink have been demonstrated successfully makes it highly suitable for the printing of the valuable products, viz., currency, passports, pharmaceuticals, etc. for...
Focused ion beam (FIB) deposited tungsten is reported to have a superconducting transition temperature of ~5 K (1), as it forms an amorphous alloy comprising of W, Ga and C. Here we report the fabrication and superconducting characteristics of meander structure of tungsten deposited by FIB technique. Two such structures were fabricated with varying...
We report superconducting properties of tungsten meander structures fabricated using the focussed ion beam (FIB) induced technique. Three meander structures with individual line widths of ~70 nm, ~300 nm and ~450 nm were fabricated for evaluation and comparison of the superconducting properties. The resistance-temperature characteristics of the mea...
