                                                                ABSTRACT 

Molecular electronic materials such as conjugated polymers, organic molecules and Biomoleculeshave attracted immense interest for applications in solar energy conversion as well as to light emission, thin-film electronics and molecular electronics. The appeal lies in the potential to tune material properties (electronic, optical, mechanical and thermal) through control of chemical structure and molecular packing, whilst using facile fabrication methods. Achieving this goal has been challenging, due to the intrinsic disorder and structural heterogeneity of the materials and the lack of appropriate device-physics models to relate structure to physical properties. Recent developments in materials design, computational modelling and experimental characterization have led to the demonstration of improved molecular materials systems for electronic devices. In this talk, I will present that how organic molecules and bio-molecules can be incorporated in molecular devices. Firstly, I will be discussing about challenges in molecular electronics and how molecules can be used in devices. Secondly, I will be focusing on electron transfer mechanisms of biomolecules in solid state and role of electrode-protein coupling in Biomolecular electronics. In the end, I will conclude with discussion on my future plans, where I will be focusing on utilization of IETS (inelastic tunneling spectroscopy) in the study of electron transport mechanisms in Bacterial nanowires and photoactive multilayers of proteins in solid state, so that they can be utilized in the real time devices. 

      Biography:   

Kavita Garg has obtained her Ph.D. degree in 2013, as a DGFSFellow from Bhabha Atomic Research Centre in chemistry with a specialization in molecular electronics. She has been awarded DST young scientist Fellowship in 2014, with which she was employed at IITB and IISc Bangalore, India for three years. In 2017, she joined as a postdoctoral fellow at WIS, Israel, in Prof. David Cahen Group. Where she has worked on bio-molecular electronics for 2 years. After a maternity break, recently in 2021, she has joined DIT University, Uttarakhand as an Assistant Professor. Her PDF offer that was put on hold in last year due to Pandemic was revived to conduct EC-STM studies on multi-Heme proteins (from Aug 2021) at King’s College London.
