Abstract:
Our research has involved using angle-resolved photoemission spectroscopy ARPES as a nano-scale probe of the electronic structure of surfaces and interfaces of high-temperature superconductors. Photoemission has provided unique and valuable information because of its surface sensitivity, excellent energy resolution, and ability to detect core-level chemical shifts. The information has strong implications for a fundamental understanding of the electronic structure of the cuprates as well as the construction of practical devices such as Josephson junctions. We will focus on 1 description of custom-designed thin film samples of high temperature superconductors HTSC and the development of methods to study them with ARPES, 2 electronic structure measurements using ARPES, including the measurement of energy gaps, 3 the implications for characteristics of devices using HTSC, and 4 proximity effect searches.
