摘要：

We report the first measurements of resistivity for a ring-shaped crystal of the quasi-one-dimensional conductor NbSe3. The temperature dependence of resistivity and current-voltage characteristics clearly demonstrate that the one-dimensional chains are along the circumference of the ring and the charge-density wave (CDW) can slide along the ring above a threshold field. The ring crystal is suitable for the investigation of interference phenomena in the CDW system. We also find that the ring crystal cannot be regarded as two CDW conductors connected in parallel.
