Identification Procedure of Room-Temperature Quantum Spin Hall Topological Edge State
Princeton Docket # 24-4088
This groundbreaking technology represents the first realization of room temperature topological states, a significant advancement in the field of quantum materials. Topological insulators, known for their insulating bulk and conducting surface states, have long been limited by the need for extremely low temperatures. This innovation overcomes that barrier, enabling practical applications in consumer electronics without complex cooling systems.
The technology provides a robust methodology for identifying and characterizing new room temperature topological materials, including detailed criteria and experimental procedures. It employs vector magnetic field application to confirm the presence of true topological states and utilizes variable temperature scanning tunneling microscopy to identify room temperature quantum spin Hall states. These room temperature topological materials have potential applications in low-power electronics, spintronics, quantum computing, and high-performance sensors, potentially revolutionizing various sectors of the electronics industry.
