Stellhorn Lab
About the lab
To understand how materials or devices are functioning, it is crucial to comprehend their structure at a fundamental level. Our research laboratory specializes in the atomic resolution structural analysis of functional materials, focusing on uncovering the intricate structure-property relationships that define material performance. By leveraging advanced quantum-beam techniques, such as X-ray diffraction and spectroscopy, we probe the local atomic structure, revealing detailed insights into how these materials operate. Through precise atomic-level characterizations, we aim to bridge the gap between structure and functionality, to provide innovations in material science and technology.
