About

I introduce myself as Prof. Somaditya Sen, an experimental Condensed Matter Physicist in the Physics department at the Indian Institute of Technology Indore, with interests in Material Science, Electronics, Communications, and Biomaterials related to Oxide Materials.

I have been a professor in the Department of Physics since 8th May 2023. I joined the department as an Associate Professor on 10 October 2013. Before that, I served at IIT Indore as a Visiting Associate Professor in the Center for Surface Sciences and Engineering from February 2013. At IIT Indore, I have served as a member of the Board of Governors and as the Associate and Officiating Dean of Planning during the institute's initial phase, when it was going through its most challenging time of transitioning from the temporary campus to the permanent one. Presently, I am also a Consultant Faculty at King Fahd University of Petroleum and Minerals. From Sept 2017 to Sept 2020, I served as an Adjunct Associate Professor at the Ming Chi University of Technology in Taiwan.

I work on structure-correlated physical, optoelectronic, energy, and electrochemical properties of magnetic and nonmagnetic oxide semiconductors. Bulk and thin-film samples are prepared of extremely chemically homogeneous doped and co-doped simple and complex (perovskite/double perovskite) oxides. The primary thrust is to analyze the structures of chemically modified compositions using XRD, followed by Rietveld refinement of the XRD data. Vibrational properties are studied thereafter to correlate structural changes with lattice strain and other subtle changes in the materials. The electronic properties, such as bandgap, lattice deformation, defect levels, transport properties, carrier properties, etc., are studied. The applicability of these materials is investigated, including ferroelectricity, dielectric and transport properties, electrochemistry, photocatalysis, photosensitivity, chemosensitivity, etc. A new approach to utilizing high-dielectric-constant materials with low losses is being investigated in the context of dielectric resonator antennas.

Single-phase materials are a major focus of my research, with electrical (conductivity, dielectric, ferroelectric, piezoelectric, thermoelectric, sensitivity, etc.), optoelectronic (bandgap, defects, band-tailoring, etc.), mechanical, and many other aspects investigated.

My collaborators are in the USA, France, China, Taiwan, Japan, Saudi Arabia, and India.
