IIT-Delhi’s new device exceeds 6G tech with terahertz radiation

A groundbreaking development was announced on Tuesday by an international team of researchers led by the Indian Institute of Technology (IIT) Delhi, signaling a leap forward in communication technology beyond the current capabilities of 6G. The newly unveiled device, termed a Spintronic Terahertz (THz) emitter, operates through a sophisticated bilayer system integrating ferromagnetic and non-magnetic materials.

According to the team hailing from IIT-Delhi’s Centre for Applied Research in Electronics (CARE) and the National University of Singapore, this emitter utilizes a unique combination of platinum and cobalt layers to create a semimetal material capable of generating intense pulses within the terahertz frequency spectrum.

Rahul Mishra, Assistant Professor at CARE, highlighted the device’s dual objectives of bolstering emission strength while ensuring efficient operation at room temperature, thereby rendering it suitable for practical, real-time applications.

Professor Samaresh Das emphasized the transformative potential of THz technology, particularly in the field of medical imaging, where it promises safe visualization of the human body’s interior. Additionally, research scholar Pinki Yadav underscored its capacity to revolutionize wireless networks by enabling faster and more secure connections, thus enhancing the speed and reliability of internet access.
