Superconductivity, high critical temperature found in 2D semimetal W2N3

2D superconductors have drawn considerable attention both for the fundamental physics they display as well as for potential applications in fields such as quantum computing. Although considerable efforts have been made to identify them, materials with high transition temperatures have been hard to find. Materials featuring both superconductivity and non-trivial band topology have proven even more elusive. A recent Nano Letters paper predicts just such a material in the easily exfoliable, topologically non-trivial semimetal W2N3.
