Surajit received his PhD in experimental Condensed Matter Physics from Indian Institute of Science,
Bangalore, and then followed with a Post doctoral stint at the National University of Singapore before
joining IISER, Bhopal.
Surajit has been exploring the role of lattice vibrations, aka phonons, in materials and their novel
properties. At finite temperatures, phonons play an important role, often dictating the materials
properties. Phonons in solid state systems and across the interfaces can interact with various
quasiparticles or collective excitations, such as, charge-carriers, spins, orbitals, impurities, defects,
and the phonons themselves. Such interactions can be enhanced or attenuated by engineering the
material by appropriately tailoring its structure, geometry, composition, temperature, and other
relevant parameters. Surajit's group at IISER, Bhopal, envisions to develop phonon-engineered smart
materials suitable for device applications such as electronic, optical, optoelectronic, thermoelectric,
magnetic, and spintronic devices, as well as energy conversion applications.
