9624603 Tuominen This experimental research project is designed to help advance the science and technology of nanostructure single-electron devices. The first research objective of this project is to utilize single-electron device techniques to explore and understand several key issues in mesoscopic superconductivity: even-odd electron number physics, the physics of macroscopic quantum variables, and coherent charge transport through superconducting-normal metal interfaces. The second objective is to investigate -- and precisely control -- the quantum interaction `etween single-electron devices and their electromagnetic environment by utilizing the powerful techniques of cavity quantum electrodynamics. The 60 nanometer-scale devices used in this work will be fabricated using electron-beam lithography, thin-film metallization, and microelectronics clean room techniques. An ultrahigh vacuum thin-film deposition system will be constructed to provide a major advancement in the nanostructure device fabrication technology. Measurements will be performed at cryogenic temperatures (10 mK to 10 K) using lownoise electronic transport measurement instrumentation. The overall goal of these research activities is to establish a strong scientific foundation for single-electron device physics, and help it progress toward what may become the ultimate level in electronics technology. %%% The objective of this experimental research project is to advance the science and technology of single-electron devices.
