Quantum Heterostructures and Device Physics Lab @ LSU
Welcome to the Ngabonziza Research Group
Our Lab is in the Department of Physics & Astronomy at the Louisiana State University (LSU). Our research is at the interface of Condensed Matter Physics, Materials Science & Engineering Physics. We focus on the epitaxy of quantum materials and heterostructures; and the exploration of novel functionalities in quantum devices fabricated from thin films and heterostructures.
The goal of our research lab is to design and realize novel electronic systems; and to explore their practical applications for device physics that have potential technological applications in quantum electronics, spintronics; as well as in energy and environmental sciences.
Assistant Professor of Physics – Louisiana State University
Current Research Interests include
Complex Oxide Heterostructures
Our research interests are on transparent conducting oxide heterostructures for applications in the next-generation of transparent electronic devices; and on ionic conducting oxide heterostructures for applications in clean energy technologies
Correlated Electron Systems
Research interests are on 4d correlated electron systems; in particular, ruthenates and/or magnetic functional materials (e.g., strontium ruthenate oxides of the Ruddlesden Popper phases). These systems exhibit complex interplay between the charge, spin, orbital and lattice degrees of freedom.
We use single crystals, thin films and heterostructures of these materials to explore their unique magnetic/electronic properties.
Topological Quantum Materials and Thermoelectricity
We explore the potential of topological insulator boundary states for thermoelectricity to realize a variety of high-performance thermoelectric devices.
Combined studies of thin film growth and characterizations, as well as quantum transport explorations of novel functionalities in nanoscale topological devices are performed.
