Nanoscale magnetism, Spintronics, Materials for solar energy
As dimensions of materials cross over fundamental length
scales, new physics emerge. We are interested in understanding
fundamental spin and magnetic phenomena in materials at reduced
dimensions, such as 2D thin films, 1D nanowires and 0Dnanocrystals.
We grow these materials using both chemical solution phase
synthesis, and physical and chemical vapor deposition techniques.
Doping, alloying and heterostructures are exploited to modify the
properties of the host materials. We use magnetic,charge transport
and magneto-optical probes to study the physical properties of
these materials. While our research focuses on basic science,
it is strongly driven by future applications in information
technologies, renewable energy and biomedicine.Presently, the
topics of our research include: studying magnetic effects in
atomically thin transition metal chalcogenide films; developing
novel magnetic nanostructures for advanced magnets, data storage
and spintronics; developing novel magnetic nanoparticles for
bio-imaging and magnetic hyperthermia.
We are also interested in the design and development of novel
materials for energy harvesting applications. Our experimental work
is guided by first principles theory and materials informatics.
Presently our project is focused on developing chalcogenide
perovskites, an emerging class of unconventional
