Project Detail
Objective on the basis of need

To develop highly sensitive, selective, and reliable gas sensors by integrating 2D materials with CMOS-compatible FETs.

Executive summary of the proposed project (In 250 words)

Globally, there is an increasing need for state-of-the-art gas-sensing technologies as environmental and industrial safety become primary considerations. The drawbacks of conventional gas sensing methods must be addressed, such as surface reactions, poor selectivity, high operating temperatures, and practicality in real-world situations. By developing and manufacturing gas sensors with two-dimensional (2D) materials integrated with field-effect transistors (FETs) that are compatible with complementary metal-oxide-semiconductor (CMOS) technology, this project seeks to revolutionize the field of gas sensing technology. The goals include the development of 2D semiconductors and surface modification to increase sensitivity, integration with CMOS technology, and the formidable task of precisely detecting dangerous gas concentrations. Our goal with this project is to overcome the present obstacles and pave the way for developing extremely sensitive, CMOS-compatible, and selective gas sensors.
