We report studies of o-TaS3 nanocrystals, including sample preparation of nanocrystals, fabrication of electrodes attached to the nanocrystals, and transport properties. Absence of the clear Peierls transition and one-dimensional variable-range-hopping conduction were observed. We also found finite-size effect of soliton transport in nanoscale o-TaS3 crystals. These results are consistent with the idea that electric transport phenomenon of the nanoscale o-TaS3 crystals should be attributed to soliton nucleation.
