Our group researches light-matter
low dimensional semiconductor nanomaterials and related hybrid and
heterostructures, with particular emphasis on optoelectronic relevant
interfacial phenomena like charge and energy transfer. We believe these
nanomaterials have tremendous potential in the development of next generation
solar cells, solid state lightning, nanophotonic and quantum material based devices.
We investigate atomically thin 2D van Der Waals materials, colloidal quantum
dots, metal nanoparticles and nanostructures, conductive polymers and biological
systems such as natural light harvesting antennaes.
We often develop self-assembly methods to construct nanohybrids in search of emerging optoelectronic properties
and improved optoelectronic performance .
We use ultrafast pump-probe, linear and nonlinear
microscopy/spectroscopy to investigate the performance of
these nanomaterial hybrids. Past and current research is described here
and our most recent publications are listed
here. Our group manages the
Facility of the Center for Functional Nanomaterials which is a
collection of state of the art ultrafast optical techniques,
including pump-probe, linear and nonlinear based metohds for soft, hard and biological materials
characterization, with some methods having single nanostructure/nanocrystal
