Designing dislocation-driven polar vortex networks in twisted perovskites
William Sandholt, Nicolas Gauquelin, John Mangeri +21
Twisting two atomic layers produces a geometric moire pattern, but bonding-induced interfacial reconstruction fundamentally transforms this into an ordered dislocation network - a…
Fully characterized linear magnetoelectric response of 2D monolayers from high-throughput first-principles calculations
John Mangeri, Thomas Olsen
We screen 4784 stable monolayers from the Computational 2D Materials Database (C2DB) and identify 57 ferromagnetic (FM) and 67 antiferromagnetic (AFM) compounds that should exhibit…
Magnetoelectric behavior of breathing kagomé monolayers of from first-principles calculations
John Mangeri, Varun R. Pavizhakumari, Thomas Olsen
We apply density functional theory to explore the magnetoelectric (ME) properties of two-dimensional . These compounds have recently been propose…
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…
