Research Overview
A main research interest I follow is the electron transport mechanism in various systems. In my doctoral thesis, I have explored active layer morphology of bulk-heterojunction polymer based solar cells utilizing commercial, custom-made Near field Scanning optical and force microscope. In post-doctoral position, I moved my research emphasis to the field of (bio)molecular electronics, to understand electron transport pathways particularly in proteins and peptides.
Highlights of Recent Activities
At current position, my research is directed towards the development of combined experimental and theoretical methodologies to explore charge transport through thin organic molecules (SAMs) with nanometer-scale dimension devices. The study aims to reveal and correlate charge transport characteristics with the structures (chemical, physical, and electronic) of the molecule. These correlations will be the basis for a qualitative analysis and eventually quantitative one, focusing on “electronic coupling" and "molecular interface" based theory of charge transport.
