Aryabhatta Knowledge University (AKU) has received a patent for a novel yttrium-based semiconductor nanomaterial, Yttrium Aluminium Borate (YAB), which offers significant improvements in LED lighting technology. Developed by a team led by Dr.
Bibhuti Bikramaditya, the material exhibits strong semiconductor properties, including an energy band gap of 1.28-1.33 eV, enhancing luminous efficiency and color quality while reducing operational voltage to 1.7 volts. The YAB technology addresses limitations of current LED systems, notably their dependency on rare-earth elements sourced from China, by being lanthanide-free and potentially sourced within India.
Prototyping is underway at Smartway Electronics, with collaboration from the Indian Institute of Technology Patna. This advancement signifies a critical step toward strengthening India's semiconductor industry and reducing import dependency.
