The 2014 Nobel Prize in Physics was awarded for “efficient blue light-emitting diodes (LED) leading to bright and energy-saving white light sources” recognizing painstaking research over many decades into the world of nitride semiconductors. Nitrogen-containing compound semiconductors are key materials for compact, high-efficiency LED light sources. The speaker traces a historical journey through the exciting world of LEDs highlighting the contributions of the Nobel Laureates, and looks at the challenges as well as the amazing possibilities opened up by these devices. 

About the speaker: Prof. Arnab Bhattacharya, a scientist with research interests in semiconductor optoelectronics set up India’s first nitride semiconductor epitaxial growth lab at TIFR. A passionate science communicator, Arnab pioneered “Chai-and-Why?” Mumbai’s popular science café and presently chairs Science Popularization and Public Outreach at TIFR.

This was part of the National Science Day celebrations at IUCAA.
