China亿电竞平台 Powder Net News In a study published in the亿电竞 journal Nature by a research team led by Rutgers University, electrons will organize into stripes in the亿电竞 presence of moire patterns in graphene, which can help to find quantum materials working at room temperature, such as superconductors. Such materials will greatly reduce energy consumption and make power transmission and electronic equipment more efficient.


The亿电竞平台 team studied twisted bilayer graphene, which consists of two layers of graphene superimposed and slightly misaligned. This creates a "twist angle," which produces a moire pattern that changes rapidly as the亿电竞 twist angle changes.


"Our results provide an important clue to link a type of graphene called twisted bilayer graphene with superconductors that can work at room temperature," said EVA y. Andrea, a physics professor at Rutgers University


In 2010, Andrea's team found that, in addition to aesthe亿电竞tics, moire patterns formed by double twisted graphene have a significant impact on the亿电竞 electronic properties of materials. This is because the亿电竞 moire pattern slows down the亿电竞 conductive electrons in graphene, causing the亿电竞m to cross each othe亿电竞r at extremely high speeds.


Previous studies have shown that when graphene meets the亿电竞 "magic angle superposition" of 1.1 degrees, electrons can conduct electrons with almost zero resistance and become superconductors.


Using a technique developed by Andre's team to study twisted double-layer graphene, the亿电竞 team found a state in which electrons organize the亿电竞mselves into strong, hard to break stripes.


"Our team found that this feature is very similar to similar observations in high-temperature superconductors, which provides new evidence for the亿电竞 deep connection of the亿电竞se systems and opens a new way to unravel the亿电竞ir long-standing mysteries," Andre said
