Light-Matter Interactions in 2D Materials
Our research investigates light–matter interactions in two-dimensional materials, where atomic-scale thickness gives rise to unique optical phenomena that do not exist in conventional bulk materials. We study how photons interact with charge carriers, excitons, defects, and lattice vibrations in atomically thin semiconductors, with the goal of understanding and controlling their optical response. By combining advanced spectroscopy, device fabrication, and materials engineering, we develop strategies to tailor light absorption, emission, and photocarrier generation for applications in photodetectors, photodiodes, transistors, and next-generation optoelectronic technologies.
Two-dimensional (2D) materials, have excellent mechanical properties, while exhibiting semiconducting electrical characteristics. Therefore, they hold a promising potential to be core elements in photoelectronic devices, mechanical resonators, electrical components, and more. We study the mechanical, optical, and the electrical properties of 2D materials and the coupling between them. We also build nanoelectromechanical (NEMS) devices with 2D materials integrated as transduction elements, such as sensors and resonators. The 2D materials under investigation include graphene, transition metal dichalcogenides, boron-nitride, group III-monochalcogenides, and more.
Two-Dimensional Devices and Properties
Foam Nano-materials
Foam nano-materials are three-dimensional networks of 2D materials that present a porous microscopic structure. As such, they present physical properties that are different from their 2D counterparts, such as high flexibility and ultra-high surface area. We study their mechanical, electromechanical, and thermal properties and use this knowledge to build foam-based functional devices.
We study several foam nano-materials, such as graphene, boron-nitride, and boron carbonitride foams.
