Exploring Chemistry and Physics at the Nanoscale Using Mechanically Controlled Break Junctions
The use of single molecules as circuit elements represents the ultimate in device miniaturization. The mechanically controlled break junction (MCBJ) technique is a commonly used method for the formation of metal-molecule-metal junctions. Using MCBJs, the electrical properties of single molecules can...
