"Atom to Devices"

Our Research Strategically Focused on Three Main Research Themes:

Quantum Materials for next generation Quantum Technologies

In the FMD Lab we engineer Quantum Materials. However, the device-compatible fabrication and experimental identification of Quantum Materials remain challenges due to the complexity involved in materials growth and controlling quantum functionalities, which are addressed in our lab. Various degrees of freedom of Quantum Materials, highly sensitive to external stimuli (e.g., electric/magnetic field, and pressure), are investigated at the nanoscale to realize exotic functionalities like Mottronics, magnetoelectrics, topological electronics, and quantum computation. 

Magneto-caloric materials for Solid State Refrigeration

Existing cooling techniques include absorption and adsorption refrigerators, thermoelectric cooling, thermoacoustic refrigerators, ejector refrigeration systems, magnetocaloric refrigeration, etc. Among these, magnetocaloric effect is the most promising candidate due to its efficiency and environmental friendly approach. We investigate different strongly corelated materials and Quantum Materials for future magneto-caloric refrigeration.

Non-volatile memory (NVM) for Energy-Efficient Neuromorphic Computing

We investigate different nanoscale functional materials (with at least one dimension below 100 nm) for use in energy-efficient Non-volatile memory (NVM) for Energy-Efficient Neuromorphic Computing. We focus on manipulating metallic alloy and strongly correlated oxide materials, and their spin-ion-charge interactions at the nanoscale. The materials are prepared by various state-of-the-art deposition facilities such as DC/RF sputtering, Pulsed Laser Deposition (PLD), and thermal evaporation. We also use different computational techniques such as Micromagnetic simulations, and Density functional theory (DFT) to design and understand materials systems.

Computation 

Density-functional theory (DFT)  

We use Density-functional theory (DFT)  as a valuable tool to understand magneto-electric interaction at atomic level. IISER TVM has excellent High-Performance Computing facility. Tuhin is associated with High-Performance Computing (Center for HPC).

Micromagnetic simulations 

We use micromagnetic simulations (e.g. OOMMF) as a valuable tool to increase our understanding of nanoscale magnetic systems, optimize magnetic nanostructures and guide our magnetic experiments through parameter spaces that would otherwise be difficult and expensive to navigate.

We also do DFT calculation in collaboration to understand magneto-electric interaction at atomic level.
