High Responsivity Gate Tunable UV-Visible Broadband Phototransistor Based on Graphene-WS2 Mixed Dimensional (2D-0D) Heterostructure
Shubhrasish Mukherjee, Didhiti Bhattacharya, Sumanti Patra +5
Recent progress in the synthesis of highly stable, eco-friendly, cost-effective transition metal-dichalcogenides (TMDC) quantum dots (QDs) with their broadband absorption spectrum…
Experimental and theoretical demonstration of negative magnetization induced by particle size reduction in nano-form GdCaMnO
Papri Dasgupta, Sanjukta Paul, S. Kumar +2
We report a pervasive phenomenon of gradual emergence of negative magnetization in typical MnO orthorhombic perovskite manganites in nano form (with being…
Study of the ferromagnetic-insulator phase in manganites
Sanjukta Paul, Sudhakar Yarlagadda
Understanding the coexistence of ferromagnetism and insulating behavior in manganites is an unsolved problem. We propose a localized-band model involving effective intermediate-ran…
Giant magnetoelectric effect in pure manganite-manganite heterostructures
Sanjukta Paul, Ravindra Pankaj, Sudhakar Yarlagadda +2
Obtaining strong magnetoelectric couplings in bulk materials and heterostructures is an ongoing challenge. We demonstrate that manganite heterostructures of the form ${\rm (Insulat…
