Researchers at IIT Gandhinagar (IIT-Gn), in collaboration with Penn State University, have developed a cutting-edge solution for miniaturizing semiconductors using titanium diboride nanosheets as gate insulators. This innovation is set to revolutionize future chip technology by enabling the creation of smaller, faster, and energy-efficient 2D transistors—paving the way for advancements in areas like quantum computing and next-gen electronics.
Pioneering Research
The team’s work, recently published in ACS Nano, showcases titanium diboride nanosheets as promising gate insulators for atomically thin transistors. Gate insulators are vital in semiconductor devices, regulating electric current and minimizing leakage, which enhances both performance and reliability.
By leveraging a newly discovered room-temperature process in IIT-Gn’s labs, the researchers have transformed titanium diboride into stable nanosheets, demonstrating excellent dielectric applications—an area where earlier materials had varied success rates.
Key Scientific Achievements
-
The study is one of the first demonstrations of titanium diboride in this context, with results showing near-ideal parameters for semiconductor applications.
-
Boride-derived nanosheets present a unique balance of low equivalent oxide thickness (EOT), low defect density, and strong switching performance.
-
The approach promises room-temperature, large-area compatibility, making it industrially viable for wide-scale semiconductor fabrication.
Leadership Comment
Prof Kabeer Jasuja, IIT-Gn, commented on the breakthrough: “This study opens new doors in electronics, showing that boride-derived nanosheets—largely unexplored until now—can deliver a delicate balance between performance and reliability.
It signifies a leap beyond traditional materials, providing a scalable pathway to create advanced 2D transistors with energy efficiency and speed at their core”.
Global Collaboration
The project benefited from expertise in device fabrication and benchmarking provided by Prof Saptarshi Das’s group at Penn State.
Doctoral student Anshul Rasyotra also contributed significantly to the research during a six-month stint in the US lab for hands-on nanosheet testing.
This advancement positions IIT-Gandhinagar on the frontlines of semiconductor innovation and heralds a new era for compact, high-performance electronics.
