Current Research
The field of “molecular electronics (ME)” aims to manipulate charge-transport properties by varying molecular structures and functionalities, thickness positioned between electrodes.1 Molecules are the primary building blocks can be used as circuit elements and creation of molecular devices of dimension possibly much smaller than existed silicon-based devices. Thanks to the molecular flexibility which offer tremendous opportunities and challenge the traditional silicon-based electronics. Our research group at IIT K focus on creation of Molecular Junctions by replacing conventional metals as top and bottom contacts. Till date, well studied “molecular electronics” employs metal-molecule-metal (MMM) configuration. However, the MMM suffers due to its less stability, and more importantly can create short circuit if there are some pinholes present at the template layers/bottom contacts/Self-assembled monolayers (SAMs). In this regard, carbon-based molecular electronics act as a great alternative, as sp2 carbon has been a promising electrode material which can make strong covalent bonds between the carbon electrode and organic molecules through diazonium reduction and are highly stable up to 300 oC.2 Interestingly, thickness of the molecular layers can be controlled by electrochemical grafting conditions which can be achieved either by controlling the electrochemical window or by changing the voltammogram cycles.3 The top contact such as e-beam carbon of 10 nm thickness can be deposited over the molecular assemblies in order to prepare the carbon-molecule-carbon “molecular junction”. We intend to study fundamental understanding of stimuli responsive charge transport across the organic, inorganic complexes, biomolecules (such as redox-active proteins, enzymes). Opto-electronic properties of the molecular based devices can be tuned easily by changing the molecular structures, functional group, thickness, which can’t be achieved using the silicon-based devices. We are also interested in studying spintronics phenomena on carbon-based ferromagnetic devices, where functional organic molecules will be the spin transport media.
