• Semiconductor Device Modeling & Simulation - from Materials to Devices to Circuits

Our earlier work here mostly targeted next-generation (silicon/germanium based) logic/memory transistor technologies. These days, it is oriented more towards wide-bandgap material (e.g. GaN, SiC) based transistors for high-speed and high-power applications. Our interests have been to connect materials modeling to device design, and device design to circuit simulation; and to explore multi-physics phenomena. We use a combination of commercial simulation tools as well as simple tools developed in-house (e.g. MATLAB based, especially for aspects of device modeling).

• Quantum Biomimetic Technologies - for Sensing and Metrology

These are technologies inspired by Quantum Biology - the study of biological systems where quantum mechanics might be playing a non-trivial role. Our earlier work here was on the Avian Compass - terrestrial magnetic field sensing by migratory birds which enables their navigation, and biomimetic magnetic field sensing based on similar principles. At this time, we are focused in particular on Quantum Biomimetic Olfaction, aka Quantum Electronic Nose. Police dogs sniffing for drugs or explosives at public hubs hint at the fact that our electronic nose sensors are yet to achieve the power of biological olfaction, the sense of smell. Realization of such sensitivity in man-made sensors would be a path-breaking development for myriad applications, like food/agri-tech, industrial automation, healthcare, environment, and defence/aerospace. The short-to-medium term goal is to design and realize an electronic nose sensor inspired by biological olfaction, specifically the Vibration Theory of Olfaction (which posits that it is transduced by an inelastic tunneling process). Our work has spanned atomistic device design, sensor circuitry design, and application of machine learning for odorant classification. The long-term vision here is to digitize smell, i.e. to convert olfactory information into electrical signals, to store communicate and recreate it - similar to what we routinely do with audio and visual information today. A new by-product for us of this olfactory sensing research is the exploration of inelastic tunneling based semiconductor metrology.
