MEMS and NEMS sensors for chemical and bio-molecules: One of the major research focusses of the NESL group is detection of chemical and bio-molecules.  To perform this detection, we use microcantilevers (resembling tiny diving boards) to sense the change in electrical, mechanical, chemical properties caused due to adsorption of the target    molecules. We are also focused on using nanostructures as resonating elements for detection,   taking advantage of their unique physical properties.	Potentiometric measurement set up APL, 2007
MEMS Simulations using ANSYS: Microcantilevers are being modeled and simulated using ANSYS finite element simulation software. The experimental data and theoretical modeling results are being correlated to achieve greater understanding about the mechanics and dynamic behavior of the cantilevers and their applications in molecular detection.
Scanning probe microscopy: Our group is engaged in developing special scanning probe modes for characterization of nanowires and nanoparticles. Nanoscale capacitance and current-voltage measurements are one of the major focus at this point. Samples investigated using these special SPM modes include special semiconductors for sensing applications, bio-nano particles, and inorganic nanowires.	Te precipitates in CZT, APL 2007
Micro and Nanoelectronics: We are also investigating the properties of wide bandgap materials and devices with special emphasis to their material properties and device behavior. Growth and characterization of semiconducting nanowires is also being performed in an attempt to understand nanoscale electronic properties.
