Decoupling the Roles of Defects/Impurities and Wrinkles in Thermal Conductivity of Wafer-scale hBN Films
Kousik Bera, Dipankar Chugh, Aditya Bandopadhyay +3
We demonstrate a non-monotonic evolution of thermal conductivity of large-area hexagonal boron nitride films with thickness. Wrinkles and defects/impurities are present in these fi…
Possible signature of broken symmetry state near the quantum critical point in P doped BaFeAs: A Raman spectroscopy study
Debasmita Swain, Soumyadeep Ghosh, K. Bera +4
We study the iron-pnictide compound BaFe(AsP) for x 0.23, with a doping concentration near quantum criticality and enhanced nematic fluctuating state in t…
Analog Raychaudhuri equation in mechanics
Rajendra Prasad Bhatt, Anushree Roy, Sayan Kar
Usually, in mechanics, we obtain the trajectory of a particle in a given force field by solving Newton's second law with chosen initial conditions. In contrast, through our work he…
Analysing the anisotropy in morphological evolution and readjustment effects in cluster-cluster aggregation of AuNPs using Shannon entropy
Anurag Singh, Anushree Roy, Amar Nath Gupta
We have used information theory analogue of entropy, Shannon entropy, for estimating the variations during the isotropic and anisotropic AuNP fractal growth process. We have firstl…
Electronic band structure engineering in InAs/InSbAs and InSb/InSbAs superlattice heterostructures
Atanu Patra, Monodeep Chakraborty, Anushree Roy
We report a detailed ab initio study of two superlattice heterostructures, one component of which is a unit cell of CuPt ordered InSb_(0.5)As_(0.5). This alloy part of the heterost…
Geometrically frustrated GdInO: An exotic system to study negative thermal expansion and spin-lattice coupling
Barnita Paul, Swastika Chatterjee, Anushree Roy +4
In this article, we report negative thermal expansion and spin frustration in hexagonal GdInO. Rietveld refinement of the XRD patterns reveal that the negative thermal expans…
