In-situ spectroscopy and nanoscale electronics in superconductor-topological insulator hybrid devices: a combined thin film growth and quantum transport study

摘要

In this dissertation, we presented a combined thin film growth and quantum transport study on superconductor topological insulator hybrid devices. Understanding of the electronic properties of topological insulators (TIs), their preparation in high quality thin film form and their interaction with other materials such as s-wave superconductors and ferromagnets, is needed before TIs can be implemented in novel electronic devices. Opportunities arising from understanding the electronic properties of these materials will pave the way to the creation and manipulation of Majorana zero-energy modes, which can serve as a building block for a topological quantum bit, and to practical applications in spintronic devices.
