Coulomb Staircase

Tunneling studies between a Scanning Tunneling Microscope (STM)-controlled fine NbN tip and a NbN thin film show single electron tunneling characteristics at room temperature. The I-V curves display the Coulomb blockade and the Coulomb staircase caused by single electron charging of a series combination of two tunnel junctions. These room temperature observations indicate that it may be possible to operate single-electron-based devices in non-cryogenic regimes.

The process of ultra-miniaturization has been termed nanofabrication. It looks like the scanning tunneling microscope (STU) and related microscopes will be players in this technology of the future. One of the most recent contributions has been the demonstration that single molecules can be “pushed” across a surface with the STM. This remarkable achievement was demonstrated by Thomas Jung, Reto Schlittler, and James Gimzewski of the IBM Zurich Research Laboratory and Hao Tang and Christian Joachim of the National Center for Scientific Research in Toulouse, They were able to position intact individual molecules on a two-dimensional surface at room temperature by a controlled “pushing” action of the tip of a STM. Similar positioning feats have been done at low temperatures while thermal motion is limited.
