Scientists have discovered a revolutionary method to control super conditionivity by twisting ultra -thin layers of a superconductive material.

Twist to check the layers to control the superconduct
Scientists of the Riken Center for Emery Science (CEMS) and their employees have discovered a new way to check the superconductor by twisting ultra -thin layers of material. This breakthrough could lead to more energy -efficient technologies and progress in quantum computers. By adapting the angle between these layers, the researchers were able to precisely modify the “superconductive gap”, a key factor for the realization of these materials. Your results were published today (March 20) in Natural physics.
The superconductive gap represents the energy required for the spread of Cooper pairs. These are electron pairs that enable super conversions at low temperatures. A larger gap enables the function of super control at higher temperatures, which makes it more practical for real applications. The tuning of this gap is also for the optimization of Cooper pair -interactions on the Nanoscalawhich improves the performance of quantum equipment.
Go beyond traditional methods
So far, most efforts to control the superconductive gap have concentrated in “real space” and the physical arrangement of particles. However, the control in the “impulse room”, which orders the energy states of the system, has remained a challenge. The achievement of this precision level is crucial for the development of the next generation of superconductors and quantum technologies.
To achieve this, the group started with ultra-thin layers of Niobium disselenide, a well-known super conference that was deposited on one Graphic Substrate. With the help of advanced imaging and manufacturing techniques such as spectroscopy imaging tunnel microscopy and molecular radiation pitaxia, they precisely insert the angle of rotation of the layers. This modification generated measurable changes in the super -conducting gap in the impulse room and released a new “button” for the precise voice.
Surprising patterns and new possibilities
According to Masahiro Naritsuka of Cems, the first author of the paper: “Our results show that twisting is a precise control mechanism for super conditionivity by selectively suppressing the superconductive gap in targeted impulse. A surprising discovery was the development of flower modulation patterns within the super conductor.”
Future applications and next steps
Tetsuo Hanaguri from Cems, the last author, added: “In the short term, our research deepens the understanding of super condition systems and interactions between the layers and promotes the design of superconductors with tailor -made properties. In the long term, it lays the basis for the development of energy -efficient technologies that integrate the structure of the structure.
