Tool Development
Main content start
As an experimental research group in condensed matter physics, we are well known for developing and utilizing angle-resolved photoemission spectroscopy (ARPES) to study complex material systems. Over the last decade, we have also developed other novel spectroscopic and imaging tools, such as time- and spin-resolved ARPES, soft X-ray scattering, and microwave impedance microscopy. These methods expand our field of vision into q-space, real space, and the time domain. We have additionally developed molecular beam epitaxy systems combined with in-situ ARPES, which allow us to create new materials with atomic precision and study extreme properties of surfaces and interfaces.
