Accelerating Discovery of Metal-Insulator Transition Compounds Using Physics-Informed Machine Learning
Alexandru B. Georgescu, Peiwen Ren, Harshul Bhatt +4
Metal-insulator transition (MIT) materials are a useful platform for emerging microelectronic, optoelectronic, and neuromorphic devices, but their discovery is hindered by the high…
Symmetry-Driven Trimer Formation in Kagome Correlated Electron Materials
Varsha Kumari, Julia Bauer, Alexandru B. Georgescu
Correlated electron materials with molecular orbital states extending over transition metal clusters can host multiferroicity, spin frustration, and unconventional insulating phase…
Emerging Microelectronic Materials by Design: Navigating Combinatorial Design Space with Scarce and Dispersed Data
Hengrui Zhang, Alexandru B. Georgescu, Suraj Yerramilli +5
The increasing demands of sustainable energy, electronics, and biomedical applications call for next-generation functional materials with unprecedented properties. Of particular in…
Electronic Bound States in the Continuum in a 2D Metal
Morgan Thinel, Simon Turkel, Sebastian E. Rossi +11
Bound states in the continuum (BICs) are quantum states that remain localized despite existing within a continuum of extended, delocalized states. They defy conventional wave theor…
Tight-Binding Models for Lone Pair, Heteroanionic Solids, and Application to Layered Oxyhalides
Emily G. Ward, Alexandru B. Georgescu
We provide a methodology to understand materials with complex bonding patterns, and apply it to the example of heteroanionic and lone pair materials. We build a tight-binding model…
Engineering the Magnetic Transition Temperatures and the Rare Earth Exchange Interaction in Oxide Heterostructures
Jonathan Spring, Natalya Fedorova, Alexandru B. Georgescu +7
The properties of functional oxide heterostructures are strongly influenced by the physics governing their interfaces. Modern deposition techniques allow us to accurately engineer…
