Electronic Structure and Dynamics in Quantum Materials

Ongoing
Photoemission-based methods that interrogate solid state electronic structure have played a pivotal role in identifying and understanding key features of emerging materials. Band structure information from Angle-Resolved PhotoEmission Spectroscopy (ARPES) provided the first evidence for the d-wave

Sub-nanoscale electron microscopy of complex nanostructures

Ongoing
The properties of advance materials are becoming ever more reliant on the ability to manipulate their chemistry and structure at very fine length scales. For example, the relevant feature sizes in state-of-the-art transistors continue to decrease, even as the complexity of the architectures employed
