莫比乌斯带是通过将一条材料带扭转180°并连接其两端而产生的，从而产生独特的单侧拓扑结构。在这里，我们描述了由铌和硒的化合物NbSe 3晶体形成的莫比乌斯结构。令人惊讶的是，一个晶体带应该采取这种外来的拓扑结构，鉴于其固有的刚性，这将是预计将防止它弯曲或扭曲。
A Möbius strip is produced by twisting a ribbon of material through 180° and joining its two ends, resulting in a distinct, one-sided topology,,,. Here we describe a Möbius structure formed by crystals of a compound of niobium and selenium, NbSe3. It is surprising that a crystalline ribbon should adopt this exotic topology in view of its inherent rigidity, which would be expected to prevent it from either bending or twisting.
