Currently, we are engaged in a diverse range of projects related to

Chemical Sensor Devices: Fabrication of arrays and data collection and Machine learning based analysis.

Biosensor Devices: for detection of biomarkers for applications in diagnostics and agriculture.

Thermoelctric Materials and Devices: Bulk Thermal transport properties of solids for thermoelectric energy conversion (power generation and cooling)

Micro-thermoelectric Devices: On-chip thermoelectric device fabrication for temperature sensing and active cooling.

Spectrally Selectivity: Designing spectrally selective absorption of solar thermal and self-powered devices.The properties of matter linked to charge transport at nano-scale are key areas of interest.

The work involves tuning the physico – chemical properties of materials. This is to achieve technological applications such as listed above and allied areas. Here, one needs to understand the charge transport in low dimensional systems. This includes nanomaterials and thin films of particularly metal oxide semiconductors. These could be later exploited for technologically important device applications.

This involves the fabrication of nanomaterials and thin films. These are created by various physical and chemical methods like solution methods, CVD, and PVDs. They are then translated into an application-oriented form called a device. Further, identifying the relevant properties such as response to chemicals, temperature and electromagnetic radiation.
