Title: Superconductor – Insulator Transition in One-dimensional Nanowires


The properties of one-dimensional superconducting wires depend on physical processes with different characteristic lengths. To identify the process dominant in the critical regime we have studied the transport properties of very narrow (9–20 nm) MoGe wires fabricated by advanced electron-beam lithography in a wide range of length. We observed that the wires undergo a superconductor-insulator transition (SIT) that is controlled local processes. A qualitatively similar superconductor-insulator transition can be induced by an external magnetic field. Our results are not consistent with any currently known theory of the SIT. In the talk I will also briefly describe several collaborative projects that utilize the group expertise in nanofabrication and dynamical transport measurements.
