Molecular-scale devices hold the potential for a wide range of electronic applications requiring new fundamental scientific understanding.ÊOne of the biggest challenges in developing molecular-scale devices is to fabricate precisely and monitor the formation of the nanometer-scale electrodes.ÊWe have developed a technique that employs an applied current with feedback for controllably electromigrating a nano-scale electrode down to the quantum regime.ÊThe technique permits high-resolution imaging in a transmission electron microscope, which shouldhave far reaching applications in the design and study of these extremely small devices.
