MIT physicists find unexpected crystals of electrons in new ultrathin material

MIT physicists have discovered unexpected crystalline structures of electrons in a newly identified ultrathin material known as rhombohedral pentalayer graphene. This material, only a few billionths of a meter thick, exhibits unique properties when subjected to varying voltages at ultra-low temperatures, akin to those found in outer space. The research, published in Nature, reveals that electrons can transition between solid and liquid states, forming crystals or behaving like a liquid depending on the applied voltage. The team also identified two new electronic states, expanding on previous findings that electrons can split into fractional states. The discoveries were facilitated by advanced insulation techniques that allowed for significantly lower temperatures during experiments. The research indicates a broader family of materials with similar behaviors, suggesting potential for further exploration of exotic electronic phenomena. The findings contribute to the understanding of quantum effects in materials and could have implications for future electronic applications.
