IIT Delhi Research Team Invents Spintronic Terahertz Emitter; Read More Details Here

New Delhi: The research team at IIT Delhi’s Center for Applied Research in Electronics (CARE) has developed a new high-intensity radiation device capable of producing frequencies beyond even 6G technology capacities. 

The research behind the device and the workings and implications was also published in ACS Nano Letters, a journal by the American Chemical Society. The achievement was credited to research scholar Ms. Pinki Yadav, who designed and tested the drive under the capable guidance of Assistant Professor Rahul Mishra and Professor Samaresh Das. The project also received support from Professor Yang Hyunsoo of the National University of Singapore (NUS). 

The device is called a spintronic terahertz (THz) emitter and operates through a system made up of two layers - one layer of ferromagnetic materials and another layer of non-magnetic materials. A new semimetal material made of platinum and cobalt was also developed by the IIT Delhi team for the device. The material of the device enables it to create high-intensity pulses at a frequency of nearly 1012 terahertz. 

Professor Rahul spoke about the inspiration behind the creation of the device. “Our goal was to create an emitter that not only provides enhanced emission strength but also functions efficiently at room temperature, making it suitable for practical, real-time applications."

Professor Samaresh talked about the potential of terahertz technology, stating that "Terahertz technology, with its high-frequency radiation emission capabilities, holds the potential to revolutionize various aspects of our daily lives. Its non-invasive nature is particularly advantageous for medical imaging, enabling doctors to visualize the interior of the human body safely, without the risks associated with conventional X-rays."

The research scholar of the hour Pinki Yadav also highlighted the effect the device would have on communication technology. "In the realm of telecommunications, THz waves can facilitate faster and more secure wireless networks, significantly enhancing the speed and reliability of our internet connections."
