Abstract

The gate-controlled nanodevices were fabricated using conventional photolithography and a thin film technique. The Coulomb gap progressively decreases and disappears at a temperature of about 200 K. The measurements show that the behaviors of the Co dots on the straight tungsten-nanowire template are due to junction barriers related to Co islands as in usual single electron tunneling (SET) devices.
