Polar Charge-Ordered States in BiFeO/CaFeO Superlattice
Rajan Gowsalya, Monirul Shaikh, Sathiyamoorthy Buvaneswaran +1
Oxide superlattices represent a potent avenue for tailoring emergent electronic phases through sophisticated interfacial charge transfer and dynamic lattice distortions. This study…
Ferroelectric metal-organic frameworks as wide band gap materials
Monirul Shaikh, Sathiyamoorthy Buvaneswaran, Asif Latief Bhat +2
Wide band gap materials are particularly relevant at high temperatures. The band gap shrinkage at higher temperatures prevents device applications with narrow band gap semiconducto…
Intervention Strategies for Polarization Switching in Hybrid Improper Ferroelectrics
Ayana Ghosh, Palanichamy Gayathri, Sathiyamoorthy Buvaneswaran +1
The potential of hybrid improper ferroelectrics (HIFs) in electronic and spintronic devices hinges on their ability to switch polarization. Although the coupling between octahedral…
Polarization-Magnetization Coupling in Visible Light Ferroelectric Double Perovskites
Sathiyamoorthy Buvaneswaran, Trilochan Sahoo, Saurabh Ghosh
The bulk photovoltaic effect (BPVE), arising from broken inversion symmetry in ferroelectrics, offers a distinct pathway toward high-efficiency next-generation photovoltaics. We pr…
Unveiling Insulating Ferro and Ferrimagnetism in Double-Double Perovskite Oxides
Monirul Shaikh, Fengyi Zhou, Sathiyamoorthy Buvaneswaran +4
The emergence of ferro- and ferrimagnetic behavior in insulating materials is uncommon, largely due to Hund's rules. Utilizing symmetry analysis, first-principles methods, and clas…
