Happy to inform that my 1st Ph.D. student Ms. Kunchanapalli Ramya received her doctoral degree for the thesis entitled "Charge Transport across Organic Molecular Junctions and Perovskite Halide Crystals." It's a proud moment for me and to my lab members. She has total of 9 publications including a book chapter which are published in reputed journals of the research area. Our heartfelt congratulations to Ms. Ramya for her achievements.
She is always welcome for collaborations and discussions at our lab.

Interdisciplinary collaborations allow the to view problems from a new perspective. Congratulations to Assistant professor Dr Sabyasachi Mukhopadhyay, his PhD student Ms Ashwini Nawade, Department of Physics, and Assistant professor Dr Imran Pancha, Department of Biological Sciences on publishing a paper in the ECS Journal of Solid State Science and Technology!

Another article from our group. In this article, we described how electrode coupling between molecule and electrodes affects the optoelectronics of Bacteriorhodopsin based molecular junction using different transport modeling techniques.

One of our lab members attended Virtual Conference on Advanced Nanomaterials and Applications (VCAN 2020) conducted by Nanotechnology Research, VIT, Vellore during 17-19 Jun, 2020.

We present a thorough and comprehensive analysis of charge transport properties at solid-state protein junctions across different research groups. Various junction platforms and device configurations have been systematically evaluated, which have been found to play a critical role in determining the metal-molecules (protein) coupling efficiency at the bio-hybrid interface (in terms of contact resistance) and significantly influence the measured current densities, thus implying the importance of contact design and quality in molecular junction studies. Temperature-dependent transport measurements indicate that the charge transport mechanism is quite consistent between different junction geometries/measurement platforms (dominated by tunneling). Our conclusions are based on the unprecedented set of molecular electronic data of biomolecular tunnel junctions, which would be extremely helpful in addressing the ambiguity and discrepancy in the field, and provide important insight and guidance in optimizing the contact design/fabrication to accommodate the interfacial structural and thermodynamic mismatches, to facilitate biological charge transport studies.
