Symposium CH02-Emerging Optoelectronic and Quantum Materials—Advanced Multimodal Characterizations

Optoelectronic and quantum materials play pivotal roles in modern technologies, addressing the escalating demands of computing, data storage, and energy efficiency. As scrutiny intensifies, a profound understanding of these materials — from synthesis to device integration and operation — becomes imperative. This symposium serves as a convergence point for researchers across multiple domains, emphasizing the need for advanced characterization tools. Characterization techniques, capable of probing material properties under in situ and operando conditions with high spatial, temporal, energy, and momentum resolutions, are becoming essential. The symposium seeks to foster collaborations among diverse communities including material synthesis, device physics, optical spectroscopy, structural characterization, and materials theory. Our focus is to explore new frontiers in advanced characterizations of emerging optoelectronic and quantum materials, ranging from perovskite-inspired systems to quantum-confined materials and two-dimensional systems. The symposium underscores the synergy achieved through innovative combinations of various optical spectroscopies, scanning probe tools, synchrotron facilities, and machine learning techniques.


Topics will include:

  • Optical techniques for photophysical investigations, including advanced spectroscopies, nonlinear approaches and pump-probe methods
  • X-ray techniques, including X-ray diffraction, fluorescence, and scattering, coherent techniques and time-resolved approaches
  • Electron techniques (ARPES and ultrafast electron microscopy)
  • Advanced imaging techniques, including SNOM, STM, AFM
  • Multimodal methodologies that combine multiple complementary probes
  • Operando characterizations in device environments
  • In-situ and high-throughput approaches for materials discovery and synthesis
  • Novel methodologies for data analysis including machine learning
  • Polaron, hot carrier and exciton dynamics
  • Electron-lattice coupling
  • Defects, lattice distortion, and symmetry breaking
  • Light-induced phase changes in quantum materials
  • Chiral properties and chirality-induced phenomena
  • Electronic, magnetic, and magneto-optical properties
  • Catalytic properties and activities
