Kinetically Decoupled Electrical and Structural Phase Transitions in VO2
S. R. Sahu, S. S. Majid, A. Ahad +8
Vanadium dioxide (VO2) has drawn significant attention for its near room temperature insulator to metal transition and associated structural phase transition. The underlying Physic…
Optical control of in-plane domain configuration and domain wall motion in ferroelectric and ferroelastic
Vivek Dwij, Binoy Krishna De, Hemant Singh Kunwar +6
The sensitivity of ferroelectric domain walls to external stimuli makes them functional entities in nanoelectronic devices. Specifically, optically driven domain reconfiguration wi…
Coexistence of local structural heterogeneities and long-range ferroelectricity in Pb-free (1-x)Ba(Zr0.2Ti0.8)O3-x(Ba0.7Ca0.3)TiO3 ceramics
Koushik Dey, Abdul Ahad, Kamini Gautam +11
Environmentally benign (1-x)Ba(TiZr)O-x(BaCa)TiO (BZT-BCT) ceramics are promising materials due to their remarkable high piezoresponse [Liu…
Multiple exciton generation and giant external quantum efficiency in VO
S. R. Sahu, A. Tripathy, K. Dey +3
Multiple exciton generation (MEG) is a widely studied phenomenon in semiconductor nanocrystals and quantum dots wherein photo-excited carriers relax by generating additional electr…
Revisiting 70 years of lattice dynamics of BaTiO3: Combined first principle and experimental investigation
Vivek Dwij, Binoy Krishna De, Gaurav Sharma +4
BaTiO3 is a classical ferroelectric studied for last one century for its ferroelectric properties. Lattice dynamics of BaTiO3 is crucial as the utility of devices is governed by ph…
Magnetic correlations in subsystems of the misfit [CaCoO][CoO] cobaltate
Abdul Ahad, K. Gautam, K. Dey +7
[CaCoO][CoO], a two dimensional misfit metallic compound, is famous for its rich phases accessed by temperature, high temperature spin-state transition,…
