Interplay between Superconductivity and Nanostructure(2/2)

Project Details

Description

The proposed work is to study interplays between superconductivity and nanostructures. Owing to the condensation state of charge carriers in a superconductor is protected by an energy gap, zero resistance is a hallmark of superconductors. Charge transports in superconductors are dissipationless. Meanwhile, advances in nanofabrication and material syntheses assist production of various nanostructures. In many cases charging effect is significant due to weak coupling to the environment is built-in intrinsically in nanostructures. Level spacing in single particle states or electronic band splitting is large due to dimension constrictions. The two effects make manipulating small number of charges easily in nanostructure systems.Combining superconductivity and nanostructures in a system makes electrostatic control of superconductivity possible. Tuning superconductivity in superconductor-nanostructure hybrid systems by an electrostatic manner will extend applications of superconductivity similar to semiconductor devices. We are particularly interested in issues of how properties of nanostructures modified by superconducting proximity effect, how artificial atoms made by nanostructures interact with light fields in superconducting cavities, and what the connection is between origins of high-Tc superconductivity and 2D superconductivity. In the proposal I outline three research directions for the project. We anticipate successful execution of this project will contribute understanding and capability of controlling superconductivity in an electrostatic manner.
