High Resolution Photoemission Studies of Interfaces in High-Tc Superconductors.
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.
