Extrinsic Dielectric Response due to Domain Wall Motion in Ferroelectric BaTiO
Ashok Gurung, Mohammad Fatin Ishtiyaq, S. Pamir Alpay +2
BaTiO (BTO) is a prototypical perovskite ferroelectric, whose dielectric permittivity and loss spectra -- which are strongly temperature and frequency dependent -- include cont…
Inducing Quantum Phase Transitions in Non-Topological Insulators Via Atomic Control of Sub-Structural Elements
Thomas K. Reid, S. Pamir Alpay, Alexander V. Balatsky +1
Topological insulators (TIs) are an important family of quantum materials that exhibit a Dirac point (DP) in the surface band structure but have a finite band gap in bulk. A large…
First Principles Modeling of Topological Insulators: Structural Optimization and Exchange Correlation Functionals
Thomas K. Reid, S. Pamir Alpay, Alexander V. Balatsky +1
Topological insulators (TIs) are materials that are insulating in the bulk but have zero band gap surface states with linear dispersion and are protected by time reversal symmetry.…
Electronic and Optical Properties of Zinc based Hybrid Organic-Inorganic Compounds for Ultraviolet Applications
Trilochan Sahoo, Uchenna A. Anene, S. Pamir Alpay +1
Hybrid organic-inorganic (HOI) compounds are excellent candidates for a wide spectrum of applications in diverse fields such as optics, electronics, energy and biotechnology. Their…
Electromechanical control of polarization vortex ordering in an interacting ferroelectric-dielectric composite dimer
John Mangeri, S. Pamir Alpay, Serge Nakhmanson +1
Using a free-energy based computational model, we have investigated the response of a system comprising two interacting ferroelectric nanospheres, embedded in a dielectric medium,…
Topological phase transformations and intrinsic size effects in ferroelectric nanoparticles
John Mangeri, Yomery Espinal, Andrea Jokisaari +3
Composite materials comprised of ferroelectric nanoparticles in a dielectric matrix are being actively investigated for a variety of functional properties attractive for a wide ran…
