We successfully synthesized new crystal forms of a charge-density-wave conductor, NbSe3. The new forms are basically a loop of diameters 10-200 mum with/without a twist (ex. ring, Mobius strip). Their distinctive topology seems to offer systems for studying possible new quantum phenomena. Samples were obtained by chemical vapor transportation method and identified as NbSe3 Crystals by electron diffraction. SEM studies revealed that a loop is formed from a NbSe3 whisker that wraps around a droplet of selenium by forces of surface tension during crystal growth. Also we observed that a twist is introduced during this spooling process. Moreover, we performed transport measurements on the materials and found that, exclusively in samples with a twist, T-CDW is lower by a few K than that of NbSe3 whiskers. We suggest that the anomaly originates in local strain due to the twisted topology. (C) 2002 Elsevier Science B.V. All rights reserved.
