Terahertz Conductivity within Colloidal CsPbBr3 Perovskite Nanocrystals: Remarkably High Carrier Mobilities and Large Diffusion Lengths
Gurivi Reddy Yettapu,Debnath Talukdar,Sohini Sarkar,Abhishek Swarnkar,Angshuman Nag,Prasenjit Ghosh,Pankaj Mandal +6 more
TL;DR: These results confirm a negligible influence of surface defects in trapping charge carriers, which in turn results into desirable intrinsic transport properties, from the perspective of device applications, such as remarkably high carrier mobility, large diffusion length, and high luminescence quantum yield.
Journal ArticleDOI
Origin of the Substitution Mechanism for the Binding of Organic Ligands on the Surface of CsPbBr3 Perovskite Nanocubes.
Vikash Kumar Ravi,Pralay K. Santra,Niharika Joshi,Jeetender Chugh,Sachin Kumar Singh,Håkan Rensmo,Prasenjit Ghosh,Angshuman Nag +7 more
TL;DR: The authors' experimental results confirm that oleylammonium ions act as capping ligands by substituting Cs+ ions from the surface of CsPbBr3 NCs, and DFT calculations shows that the substitution mechanism does not require much energy for surface reconstruction and stabilizes the nanocrystal by the formation of three hydrogen bonds.
Journal ArticleDOI
Palladium Nanoparticles on Graphite Oxide: A Recyclable Catalyst for the Synthesis of Biaryl Cores
Subhankar Santra,Pradip Kumar Hota,Rangeet Bhattacharyya,Parthasarathi Bera,Prasenjit Ghosh,Swadhin K. Mandal +5 more
TL;DR: In this paper, a graphite oxide (GO) supported palladium nanoparticles (PdNPs) based catalyst was used to synthesize biaryl moieties of top selling drug molecules in a recyclable way.
Journal ArticleDOI
Fluxionality of Au Clusters at Ceria Surfaces during CO Oxidation: Relationships among Reactivity, Size, Cohesion, and Surface Defects from DFT Simulations
TL;DR: In this paper, density functional theory (DFT) calculations are used to identify correlations among reactivity, structural stability, cohesion, size, and morphology of small Au clusters supported on stoichiometric and defective CeO2(111) surfaces.
Journal ArticleDOI
Low-Bandgap Cs4CuSb2Cl12 Layered Double Perovskite: Synthesis, Reversible Thermal Changes, and Magnetic Interaction
TL;DR: A mechanochemical synthesis of CCSC is reported, its thermal and chemical stability, and magnetic response of CuII d9 electrons controlling the optoelectronic properties, which is stable in water/acetone solvent mixtures and many other polar solvents unlike Pb-halide perovskites.
