    Exploring AC Conductivity and Microstructure of Iron-Vanadium Doped Systems
    (University of North Bengal, 2025-03) Ghosh, Jiban; Bhattacharya, Sanjib
    The present work focuses on the impact of partial substitution of ZnO (former) by various other oxides in the microstructure and AC conductivity of newly developed amorphous semiconducting systems containing two transition metal ions such as vanadium and iron. The current materials may be significantly helpful in specialized applications like high-power lasers for their high refractive indices. An insightful study of the composition-dependent microstructure and electrical transport behavior with various former-modifier ratios is of great interest, not only from an application perspective but also for academic purposes.

    Na2O Doped Solid State Battery Electrolytes: Preparation and Electrical Characterization
    (University of North Bengal, 2024-03) Ram, Rakesh; Bhattacharya, Sanjib
    Present work explores the development of Na2O doped electrolytes and their conduction behavior. Electrical transport behavior (mixed conduction) of as-developed electrolytes has been investigated with respect to frequency and temperature. A nature of flat conductivity in the lower frequency window may be caused due to diffusional motion of Na+. It is also noted that the conductivity shows dispersion near the high frequency regime. Electrical conductivity has also been analyzed with respect to temperature to explore their thermally activated nature. A little bit of difference in trajectories of current-voltage characteristics in both directions should make sense for their applications in the sectors of battery-electrolytes.
