Research Abstract

Fundamental study for charge-density-wave devices which exploit macroscopic quantum states was conducted. Experiments were performed on non-local transport phenomena of bulk samples and fabrication technique of nanocrystal electrodes. A new type of non-local transport phenomenon was found in the charge-density-wave state of quasi-one-dimensional conductor o-TaS3. This is explained in terms of motion of topological defects.
