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
