IIT Delhi Researchers Unveil Breakthrough Terahertz Radiation Source for Future Communication Technologies
In a groundbreaking development, researchers at IIT Delhi have unveiled a pioneering device capable of emitting high-intensity radiation at frequencies surpassing current 6G communication technologies. Led by Assistant Professor Rahul Mishra and Professor Samaresh Das at IIT Delhi’s Center for Applied Research in Electronics (CARE), in collaboration with Professor Yang Hyunsoo from the National University of Singapore, the research team achieved this significant milestone.
The device, named a spintronic terahertz (THz) emitter, operates on a bilayer system comprising ferromagnetic and non-magnetic materials. Innovatively, the team at IIT Delhi synthesized a semimetal material using platinum in their lab, paired with a cobalt layer, enabling the emission of high-intensity pulses at terahertz frequencies approaching 1012 Hz.
Professor Rahul highlighted the motivation behind the development, stating, “Our aim was to overcome limitations of existing sources, such as narrow bandwidths and low emission strength. We envisioned an emitter functioning efficiently at room temperature, suitable for practical, real-time applications.”
The potential of THz technology is vast, as emphasized by Professor Samaresh. He explained, “Terahertz technology has the potential to revolutionize various aspects of our lives. Its non-invasive nature is particularly advantageous for medical imaging, offering safe visualization of the human body’s interior.”
Research scholar Pinki Yadav underscored the communication applications, stating, “THz waves can enable faster and more secure wireless networks, enhancing internet speed and reliability.”
The culmination of this research was recently published in ACS Nano Letters, a renowned journal focusing on nanomaterials and devices. The publication can be accessed here.
