Symposium EM3—Electronic and Ionic Dynamics at Solid-Liquid Interfaces

When interfaces are formed at the junction between materials and liquids, surprising emergent dynamical properties not present in either parent phase can spontaneously coalesce at the interface. Examples include the emergent catalytic, photochemical, electrochemical, and dynamical properties that form at solid-liquid interfaces made possible through the concerted interaction of ionic and electronic degrees of freedom between the two phases. These intriguing interfacial properties are driven by the dynamical and often coupled mechanisms operative at solid-liquid interfaces, including: ionic exchange, electron transfer, photo-excitation, strong electric fields, solvation, surface reconstructions/interphases, and non-equilibrium transition pathways. Enhanced control and understanding over coupled ionic and electronic dynamics across solid-liquid interfaces are poised to drive important material advances in energy, sensing, and computing applications; impacting broadly across fields such as low power computing, energy storage, superconductivity, solar fuels, and atmospheric carbon capture.

This symposium's primary focus is on exploring the coupled relation between ionic and electronic transfer dynamics at solid-liquid interfaces, with an eye to understanding and engineering the coupling between these phenomena. The symposium will encompass complementary theoretical and experimental characterization presentations seeking to design and map fundamental solid-liquid charge transfer dynamics near the atomic scale and at ultrafast timescales. The aim is to present leading examples over the full range of research from fundamentals to near-future energy, computing, and sensing technological applications.

Topics will include:

  • Theory and modeling of structural, chemical, and electronic properties influencing charge transfer dynamics at solid liquid-interfaces at atomic length scales and short time scales
  • Ultrafast and nano/atomic scale experimental characterization of solid-liquid interface chemical and charge transfer/transport properties
  • Atomically well defined growth of solid-liquid interfaces (within the first few nanometers) and the resulting dynamical properties
  • Novel applications demonstrating an enhanced understanding of interfacial solid-liquid charge transfer dynamics in energy devices
  • Integration into sensing and computing applications and devices
  • Strongly correlated electronic phase transitions at ionic liquid interfaces
  • Next generation synchrotron mapping of solid-liquid interface dynamics
