Research in the fabrication and physics of nanoscale devices and materials. This includes two primary research areas: nanostructures from self-assembling block copolymer templates and nanoscale device physics. The first area addresses the general scientific challenge of fabricating nanoscale structures by a convenient method and providing appropriate electrical interfacing to these structures. To adress this challenge, diblock copolymer films are used as a convenient self-assembling template for the fabrication of arrays of nanoscale elements. This results in a new fabrication method for producing integrated devices using block copolymer templates in combination with other lithographic methods. Research includes work on terabit-density single-domain magnetic arrays, magnetotransport devices, field-emission arrays, electrochemical sensor arrays, and thermoelectric cooling elements. The second research area explores issues involved in single charge transport. This includes single-electron investigations of mesoscopic superconductors and, more recently, experimental and theoretical studies on charge shuttle devices, which involves quantum charge transport coupled with mechanical vibration.
