Dilute Magnetic Semiconductors
The emerging paradigm of spintronics – solid state electronics is based on the spin property of the electron rather than the property of charge which is traditionally exploited which has provided the impetus for investigation of DMS’s (Dilute Magnetic Semiconductors). I am currently working on synthesis and properties of dilute magnetic oxide semiconducting nanoparticles. My focus is mainly on transition metal doped ZnO, SnO2 and TiO2 nanoparticles. My research interest also includes thin film semiconductors for photovoltaic applications.

Dr. E.S. Kannan
The primary research focus of Nano-materials lab is to develop hybrid materials for various electrical, optical and sensing application. We are synthesizing 1D heterostructures of metal oxides (ZnO, CuO, SnO2), multijunction ferromagnetic (Ni,Fe, Co) nanorods, and composites of 0D Transition metal chalcogenides (MoS2) nanoparticles and 2D graphene oxide using electrochemical and hydrothermal techniques. Metal oxide heterostructures and MoS2-graphene oxide composites are primarily investigated for their gas sensing and photovoltaic properties. Spin transport mechanism in 1D ferromagnetic multijunction nanorod is being investigated for developing spintronic devices.

Statistical mechanics, Interdisciplinary Physics and Physics Pedagogy
One of my current interests is in computational neuroscience where I am trying to understand auditory neuron tuning curves using simple integrate and fire models. I am also studying the depinning phenomenon, particularly the depinning of the 2D partially pinned solid (formed in the presence of a square substrate) and the associated phenomenon of peak effect. I am also interested in physics pedagogy. Some of my recent works involves mechanics of a particle on a rotating table in the presence of friction and an alternative geometric proof for the Euler's rotation theorem.

My area of interest is Spintronics. We work on thermopower measurements on metals, semiconductors and novel 2D materials, Spin Seebeck device fabrication and characterization, experiments and theory to study electron transport through magnetic tunnel junctions.
