Abstract In this study, we thoroughly explored the thermal transport and thermoelectric properties of BN-co-doped phagraphene structures in context first-principles computations combined with machine learning interatomic potential (MLIP) techniques. Our results demonstrate that doping positions can critically tune properties, offering advantages for both heat transfer applications. Notably, enhanced conductivity has been obtained 10 <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"...
We demonstrate the utility of electron irradiation as a tool to enhance device functionality graphene-analogous MoS2. With help first-principles based calculations, vacancy-induced changes various electronic properties are shown be combined result crystal-field modification and spin-orbital coupling. A comparative theoretical study possible vacancy configurations both in bulk monolayer MoS2 related their respective band-structures us explain plausible induced effects. Experimentally,...
We theoretically investigate the full thermal transport and optoelectronic features of two estab-
lished van der Waals (vdW) heterostructures based on recently synthesized monolayer C 3 N
using machinery Boltzmann GW+BSE calculations. Among structures,
C N/hBN tends to exhibit a small indirect gap semiconducting nature with an admixture com-
paratively higher 'flat-and-dispersiveness' band degeneracy in conduction minima.

Abstract In the field of optoelectronics, quantum dots (QDs) have gained interest due to easy modification electronic properties. Subsequently, importance nonlinear optical (NLO) properties is increasing day by day. this work, we systematically analyzed NLO phagraphene QDs with different shapes and sizes, employing density functional theory (DFT). A negative value cohesive energy absence imaginary modes in Raman spectra confirm energetical stability QDs. Successful experimental realization...
Abstract Phagraphene is a theoretically predicted hybridized, se‐mimetallic allotrope of graphene. The semimetallic nature phagraphene robust against external strain and B‐N co‐doping. Being experimentally realized in nanoribbon form, this quite fascinating the present scenario. In theoretical study, optical thermoelectric properties its site‐dependent co‐doped analogous configurations are critically investigated employing density functional theory. As consequence inherent rectangular...
The effect of annealing on melt spun Ni55Mn22Ga23 (at. %) ribbon has been addressed in terms structural, thermal, thermomagnetic, and magnetic field induced strain (MFIS) behaviour. In comparison to as-spun ribbons, the samples annealed within L21 domain at 1073 K for 30 h with subsequent furnace cooling, showed a rise martensitic transformation temperature. This was endorsed from electron microscopy studies revealing change morphology martensite plate stacking dislocations preferential...
Carbon-based electrical double-layer capacitors or EDLC supercapacitors have recently gained much attention due to their cost-effectiveness, environment friendliness, and stable energy supply. However, the total capacitance of is limited by quantum (QC) electrodes. In this work, we addressed effect defect-induced modifications QC introducing Stone–Wales (SW) defects in pristine phagraphene. The stability structure has been confirmed terms its dynamical, thermal, mechanical attributes. A...
We consider the log-perturbed Br\'ezis-Nirenberg problem on hyperbolic space \begin{align*} \Delta_{\mathbb{B}^N}u+\lambda u +|u|^{p-1}u+\theta \ln u^2 =0, \ \in H^1(\mathbb{B}^N), > 0 \text{in} \mathbb{B}^N. \end{align*} and study existence vs non-existence results. show that whenever $\theta >0,$ there exists an $H^1$-solution, while for <0$, does not exist a positive solution in reasonably general class. Since perturbation $ u^2$ changes sign, Pohozaev type identities do yield any The...
