Welcome to the

The Zuerch Lab at the University of California at Berkeley experimentally explores structural, carrier and spin dynamics in novel quantum materials, heterostructures and at material interfaces to answer current questions in materials science and physical chemistry. For this we pursue a multidisciplinary research program that combines the exquisite possibilities that ultrafast X-ray spectroscopy and nanoimaging offers and closely interface with material synthesis and theory groups. We employ state-of-the-art methods and develop novel nonlinear X-ray spectroscopies in our lab and at large-scale facilities. Specifically, we are interested in experimentally studying and controlling material properties on time scales down to the sub-femtosecond regime and on nanometer length scales to tackle challenging problems in quantum electronics, information storage and solar energy conversion.

    Michael named Rose Hills Innovator
    May 15 2024

    We are excited to announce that Michael has been named a Fellow in the Rose Hills Innovator Program. This accolade recognizes our project, “Quantum Crossroads: Unraveling the Mysteries of Exciton-Magnon-Phonon Interactions,” which aims to redefine the material foundations of technology through the lens of quantum mechanics. Our research investigates the intricate dynamics between excitons, magnons, and phonons within two-dimensional transition-metal phosphorous trisulfides. Leveraging our innovative cryogenic Time-Resolved Solid-State High-Harmonic Generation (TR-sHHG) technique, we explore these quantum interactions with unmatched resolution. This project not only seeks to expand our understanding of quantum phenomena but also to pioneer sustainable, high-performance materials for future computational technologies. This award propels us further towards uncovering new quantum mechanisms that could revolutionize energy efficiency and computational capabilities.

    New pre-print: Electron Transfer Dynamics at Dye-Sensitized SnO2/TiO2 Core-Shell Electrodes in Aqueous/Nonaqueous Electrolyte Mixtures
    May 5 2024

    Our latest research investigates the dynamics and efficiency of photoinduced electron transfer in dye-sensitized photoanodes using various solvent environments, analyzed through nanosecond transient spectroscopy and ultrafast optical-pump terahertz-probe spectroscopy. We observed higher electron injection efficiencies in mixed solvent electrolytes compared to aqueous and nonaqueous solvents. Specifically, the dye-sensitized SnO2/TiO2 core/shell electrodes exhibited optimal performance in mixed solvents. This enhancement correlates with the solvent-induced shifts in the TiO2 flat-band potential, influencing electron transfer dynamics. Our findings underscore the significant impact of solvent composition on the electron injection and charge separation processes at the semiconductor interface, providing critical insights for optimizing photoanode performance in solar energy applications.

    This research was done in collaboration with the Mallouk and Brudvig groups.
