Our research goal is to understand various facets of light-matter interaction for technological applications. We study how light couples with artificially engineered 3D nanomaterials to design hybrid nanostructures with enhanced functionalities. One example of functionality, for example, is controlling properties of light such as absorption, refraction or scattering while modifying intrinsic processes that represent fundamental limits to the efficiency and reliability of energy-conversion and optoelectronic devices. Studying how these microscopic interactions — like carrier-carrier, carrier-phonon or strongly correlated interactions — are modified in situ (i.e. under operating device conditions) is a major theme of our group.
Specifically, the intellectual merit of our research is to address these overarching scientific questions:
1. How a nanomaterial characteristics (crystal structure, size, morphology and interface) or its surrounding electromagnetic environment dynamically modify atomic and electronic degrees of freedom.
2. How the assembly of similar or dissimilar nanostructures result in emergent phenomena, and how to develop systematic methods to probe and enhance such desired macroscopic nonlinear effects.
3. How are intrinsic processes modified during (a) device operation or (b) growth/assembly?
We are equally interested to develop novel applications based on our research. Exploring the potential of phase-change materials, plasmonic elements and correlated systems for applications in optoelectronics, photonics, energy-to-fuel conversion and sensing are few examples.
In the coming weeks/months, we will update these sections…
