Earlier this year, scientists at MIT reported that graphene could become a superconductor if one piece of graphene were laid on top of another piece and the layers twisted to a specific angle , they called “the magic angle” of between 1 degree and 1.2 degrees. Now an international team of researchers (USA – Ohio State University, TT Dallas, Japan) found that graphene layers still superconducted at a smaller angle, around 0.9 degrees. It is a small distinction, but the findings provide a wealth of new information to help decipher the strongly correlated phenomena observed in twisted bilayer graphene and it could open the possibility of new experiments to investigate graphene as a potential superconductor in the real world…read more.
