Abstract
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.
