I am an Assistant Professor in the Department of Electrical Engineering at IIT Kanpur in the Microelectronics and VLSI stream. I had completed my Masters and PhD in Electrical and Computer Engineering from the University of Texas at Austin in 2014 and 2019, respectively, with specializations in Solid State Electronics. I received my B. Tech. degree in Electrical Engineering from IIT Kanpur in 2012. I was a Post-Doctoral Fellow at the University of Texas Austin before joining as an Assistant Professor at IIT Kanpur in 2020.
My primary research interest includes theoretical modelling of electrical transport and magnetic behavior in strong spin-orbit coupled materials, transition metal chalcogenides, transition metal dichalcogenides and topological insulators. I am currently working on modelling of coupled charge-spin transport in these materials and current induced magnetization switching mechanism on nanomagnets in proximity to these materials. The main objective of my research is to analyze the performance of these novel material-based spin-orbitronics devices for beyond spin transfer torque magnetic random access memory (beyond STT MRAM) applications. On the experimental side, I am setting up a lab for chemical vapor deposition (CVD) growth as well as magnetic and electrical characterization of transition metal dichalcogenide-based spin-orbitronics devices for spin orbit torque magnetic random access memory (SOT MRAM) applications. I also am working on modelling of electrostatics and charge transports in beyond Fin Field Effect Transistor (beyond FinFET) devices, such as nanosheets and forksheets transistors.
Topological insulators (TIs) are unique materials with insulating bulk and metallic surface states. The surface states of a TI have spin-momentum locked Dirac-type band structure due to strong spin-orbit coupling. The spin-momentum locking of the surface states provides an opportunity for manipulating the coupled spin and charge degrees of freedom of electrons on the surface of a TI by controlling one or the other. The charge current-induced spin polarization of the surface states and subsequent diffusion or tunnelling of spin current in an adjacent material, or conversion of spin current to charge current on the surface of a TI, are a few among many effects of this spin-momentum locking, which renders TIs as promising candidates for low-power spintronic applications. My research interests include theoretical modelling of TI-ferromagnet and TI-antiferromagnet based spin-orbitronics devices and subsequent experimental studies to optimize the device performances.
Transition metal chalcogenides (TMCs) and di-chalcogenides (TMDs) are two-dimensional materials with varying electric and magnetic properties, which provide platform for two-dimensional electronics and spintronics applications. TMCs can be ferromagnetic to antiferromagnetic depending on the structural compositions, and TMDS have high spin-orbit coupling suitable for spin-charge conversion. I am interested in theoretical modelling and experimental realizations of TMD based spin-orbitronics devices, as well as ab-initio calculations of TMC materials for achieving above room-temperature magnetic behavior.
