Abstract:

The goal of this cost-shared contract research was to investigate potential new three-terminal cryogenic device structures in order to explore new regimes of device physics and ultimately to develop better cryogenic superconducting devices. There were three principal thrusts during the term of this contract Submicron injection-controlled weak links ultrashort FETs with superconducting source and drain contacts which induce superconductivity in the channel, and electric field induced changes in the carrier densities of high-Tc materials. In each case our approach was to fabricate, study, and analyze experimental structures with the aim of understanding device potential. In addition to the above three terminal device thrusts, because of the enormous new opportunity that the discovery of high temperature superconductivity offered, a portion of the contract effort was directed at elucidating the basic properties of these materials with the aim of understanding their device potential.
