Ritam Chakraborty pursuing Ph.D.


Ritam did his schooling from Baranagar Ramakrishna Mission Ashrama High School, Kolkata, West Bengal. He obtained his B.Sc.(with Physics major) degree from Jadavpur University, Kolkata in 2017. Subsequently, he got masters in Physics from the same university in 2019.

Ritam joined the Computational Nanoscience group supervised at JNCASR in September,2020.

 Research Area: 

The interfaces of dye molecules and metal surfaces have unique properties that can be exploited in constructing novel devices. Ritam is using density functional theory to study such systems, motivated by scanning tunneling microscopy (STM) experiments performed in the group of Anthoula Papageorgiou and Johannes Barth at the Technical University, Munich, Germany.

Structural and magnetic study of transition metal coordinated chains of organic molecules on noble metal surfaces from First-principles: Ritam is interested in studying novel nanostructures synthesized exprimentally using semiconducting organic molecules and transition metal atoms as building blocks on metal surfaces employing first principles Density Functional Theory (DFT) calculations. His interest lies in unravelling the exotic physics embedded in the magnetic ordering of the bridging metal ions in the 1D chain or 2D monolayer. This work is being done in collaboration with the group of Prof. Dr. Johannes Barth at the Technical University, Munich, Germany.  

Study of Spin-Crossover System: He is interested in studying spin-crossover transitions of the 3d transition metal elements on-surface and also in the gas phase theoretically employing first-principles Density Functional Theory.

Study of aromaticity in organic nanostructures synthesized on surface: In this project, he is looking into the novel organic structures synthesized experimentally in the group of Prof. Dr. J. V. Barth at the Technical University Munich, Germany and am trying to unfold the novel chemistry and physics associated with it through quantum chemistry calculations.

Study of role of metal substrate on different surface chemistry shown by the self assembly of same organic molecule: He is trying to unveil the various molecule-substrate interaction present during the self assembled monolayer formation on noble metal surfaces and what role does it play on the various surface chemistry shown. This work is also being done in collaboration with the group of Prof. Dr. Johannes Barth in the Technical University of Munich, Germany.


Ritam's extracurricular interests are music, watching football, cooking and exploring different kinds of foods ranging from 'Postor bora' to 'Tiramisu'.
