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…
Monoclinic symmetry at the nanoscale in lead-free ferroelectric BaZrTiO ceramics
Koushik Dey, Abinash Tripathy, Shikha Rani Sahu +4
Local structural symmetries play a key role in the functionalities of ferroelectric materials and are often found different from average symmetry. Here, we study the real space nan…
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…
