Dr. Saurabh Ghosh

Ph.D (IACS, Kolkata)

Assistant Professor (Research)

Welcome to the 'Functional Materials by Design' (FMD) group !

Dr. Saurabh Ghosh has joined SRM Research Institute and Department of Physics and Nanotechnology as Assistant Professor (Research) in June 2017. Before  joining SRM, he worked as a postdoctoral researcher in USA from April 2011 to May 2017 (Cornell University and Vanderbilt University/Oak Ridge National Lab). In SRM, he has formed and leading the ‘Functional Materials by Design’ (FMD) group.

The objective of FMD group is to design functional materials from first principles Density Functional Theory (DFT) calculations guided by group theoretical techniques and supported by phenomenological modeling. Using DFT, structural, electronic, magnetic and many other properties of a many electron system can be determined. With the advancement of modern supercomputing capabilities, DFT is not only successful in explaining experimental findings but also predicting materials with new functionalities. Understanding the ‘structure-property’ relation of a material is the key to designing new functionalities. The group is focused on designing functional materials by tailoring ‘structure-properties’ relation those are impactful in oxide electronics, spintronics, and energy research. The FMD group will form strong collaborations with other experimental and theory groups for research activities.

Research Highligths:

Prediction of new Magnetoelectric Multiferroics (Hybrid Improper Ferroelectricity) : Perovskite ABO3 oxides display many promising functional properties including ferroelectricity and magnetism. An ongoing challenge has been to design and synthesize materials in which ferroelectric and magnetic orderings not only coexist in a single phase above room temperature, but also are nontrivially coupled. Such a cross coupling between these different ferroic orderings could lead to many novel applications, in particular, involving electrical control of magnetism (for example, in case of MERAMs or magnetic capacitors). In this direction, we have designed new route to create above room temperature “linear magnetoelectric multiferroics” in perovskite ABO3/A’BO3 superlattices, which may be amenable to advanced oxide thin film growth techniques. We have also explored possibility of polarization-magnetization coupling in insulating ferri/ ferromagnetic AA’B2O6 double perovskites, which can be realized by synthetic chemical routes.

Metal organic frameworks (MOFs) for Organic Electronics/Spintronics: In MOFs with the same topology as inorganic ABO3 perovskites, a peculiar canted ordering of the organic A-cation dipole moments governed by the symmetry give rise to a ‘weak’ ferroelectric polarization, which was previously not known. Further, our study highlights the complex interplay between strain and dipole canting and put forward the possibility of tuning of ferroelectric polarization through appropriate thin film growing and can have potential applications in organic electronics.
