Microelectronics Laboratory
This lab was developed to support the fabrication of discrete devices. It is mainly a research laboratory focusing on low cost devices and sensors for various applications. Currently, various devices such as Organic Field-Effect Transistors and Gas Sensors are routinely fabricated and characterized. Following is the summary of facilities of this laboratory
Research Themes
1. Organic and Flexible Electronics: OFETs, Circuits, and Sensors: To reduce the detrimental impact of E-waste on the earth, electronic products need to be developed which leave minimum footprints on earth at the end of their lifespan. This technology offers advantages over inorganic electronics with the possibility of development of systems on unconventional substrates that can even be of biodegradable nature. Details of this work can be found on the page of FLAME Research Group
2. Thin-Film Device and Sensor Development: Sensors based on various materials including oxide metal semiconductors, and 2D materials such as MoS2 are being fabricated for various applications using gases and pollutants. Eventual aim is to develop integrated sensors which can be enabled for IoT applications. Other Sensors such as biosensors, and MEMS based sensors are also being explored.
3. New Material and Devices: Bandgap engineering and surface studies of semiconductors, AlGaN/GaN HEMTs, Compact Modelling and Simulation
4. Hybrid Electronic Sensor Technology: HESTECH Research Group develops hybrid semiconductor devices and sensors that synergistically integrate organic/inorganic semiconductors with advanced functionalities, driving the next generation of sensor, bioelectronics, and wearable technologies. Organic Electrochemical Transistors (OECTs) use ion-electron coupling in electrolytes for highly sensitive biosensing in healthcare and environmental monitoring. OECT offers low-voltage operation, inherent signal amplification, flexibility, and biocompatibility, ideal for wearable, point-of-care, and implantable electronics. Flexible & printed electronics, made using conductive inks and nanomaterials, enable bendable, lightweight devices for various physical and chemical sensing applications.
