Indeed, materials research stands at the core of the two subjects and, meanwhile, is the unparalleled specialty of the AI-MAT. In Carbon Neutral, the atomically-thin two-dimensional materials, their associated heterostructures, and novel nano-porous materials are to form the backbone, along with functional surface modifications and atomistic defect engineering aiming at electronic-structure ameliorations and catalytic-selectivity enhancements. In Quantum Materials, we embrace the essential materials physics for future quantum device architectures. Two approaches will be undertaken, materials with emergent quantum phenomena and spectroscopic techniques to address the novel physics. The former encompasses spintronics and devices, twisted atomic layers, and semimetals with relativistic particles. The latter is to establish the temporal- and momentum-resolved spectroscopies previously unachievable in Taiwan and meanwhile powerful for the scrutiny on quantum phenomena, in addition to our core expertise of atomic-scale spectral imaging. In summary, AI-MAT will continue to be the premier research center in this ambitious MoE project and lay the solid scientific foundation for the two pressing problems of Carbon Neutral and Quantum Materials envisaged by the global community.原子級材料設計;碳中和;量子材料;Atomic materials design; carbon neutral; quantum materials
