Research Interest:

    The Advanced Functional Materials Laboratory (AFML) led by Dr. Sayan Bhattacharyya focuses on an interdisciplinary research on functional nanomaterials. The current research interests are: (A) Magnetism and Magnetotransport Properties: (i) Doped rare-earth manganite nanostructures - Modification of the conventional physical property-limits at the nanoscale; (ii) Magnetic anisotropy enhancement by confinement of nanoparticles for data storage applications. (B) Photovoltaics: (i) Quantum dot (QD) solar cells, Carbon nanotube/graphene - QD hybrid solar cells; (ii) Nano-manganite p-n junctions. (C) Confinement effects on Heterogeneous Catalysis. (D) Green Chemistry and Biological Applications - Drug delivery, Waste water treatment and Carbon Nanostructure assisted Plant Growth. (E) Metal Oxide and Chalcogenide Nanostructures - Investigation of defects, Doping Strategies and Morphology-Property Correlations.
