A research team discovered a quantum state in which electrons move in a completely new way under a twisted graphene structure. The unique electronic state is expected to contribute to the development of more efficient and faster electronic devices. It may also be applicable to technologies such as quantum memory, which can process complex computations.
Quantum physics is a crucial theory that attempts to understand and explain how atoms and particles interact and move in nature. Such an understanding serves as the basis for designing new technologies that control or utilize nature at the microscopic level. The research conducted holds significance in discovering the quantum state, which is difficult to implement with conventional semiconductor technologies, and in greatly expanding future possibilities for quantum technologies.
Graphene is a material as thin as a piece of paper and is made of carbon atoms. This study utilized a unique structure comprising two slightly twisted layers of graphene, observing a new quantum state. When compared to two transparent films, each film has regular patterns, and when they are rotated slightly, the patterns overlap to reveal new patterns.
