Abstract
We report the discovery of a Möbius crystal of NbSe3,
conventionally grown as ribbons and whiskers. We also reveal their
formation mechanisms of which two crucial components are the
spherical selenium (Se) droplet, which a NbSe3 fiber wraps around
due to surface tension, and the monoclinic (P21/m) crystal
symmetry inherent in NbSe3, which induces a twist in the strip
when bent. Our crystals provide a non-fictitious Möbius world
governed by a non-trivial real-space topology.
