Date & Time: Thursday, 25th January 2024 at 4.00 p.m.
Venue: Rajarshi Bhattacharya Memorial Lecture Hall, Chemical Sciences Building
Abstract:
The fundamental building blocks of molecular electronics are the individual molecules, which exhibit unique electronic properties. The utilization of molecular entities as active elements enables researchers to exploit quantum mechanical effects and harness novel functionalities. One of the pivotal challenges in molecular electronics is the precise manipulation and integration of individual molecules into functional circuits. As the field continues to explore the intricate interplay of non-covalent forces, it holds the promise of unlocking new avenues for device design, enabling the development of advanced, multifunctional nanoscale electronics with unprecedented performance characteristics.
In this seminar, I will first introduce molecular electronics, the electron transport mechanism in single molecular junction (SMJ), and the break junction techniques. Following this, the dynamic behaviour of hydrogen-bonded molecules in Single molecular junction and the manipulation of charge transport in π-stacked dimers will be discussed via various examples.
