We discover new ring- and tube-shaped crystals of NbSe 3 , and find a reproducibly synthesizing condition for TaSe 3 beautiful rings, as well as NbSe 3 . We confirm that the ring is a single-phase NbSe 3 crystal from the X-ray diffraction, and that a charge-density wave (CDW) transition takes place near 140 K by observing satellites of electron difraction peaks. The position of the satellites coincides with that of the conventional NbSe 3 at the CDW transition. The non-linear conduction due to the CDW sliding is also observed in the ring crystals. The threshold field is similar to the conventional ribbon-shaped Nbse 3 crystals. These results give the first evidences of existence of a CDW-ring. |
