주제 : Dimensionality Control in Artificial Superlattices

발 표 요 약 :

Artificial crystals synthesized by atomic-scale precision epitaxy is a suitable platform for realizing, exploring, controlling, and understanding the intriguing quantum mechanical regime of solid state. A judiciously designed dimensional crossover from a 3D to 2D system can be realized using the monolayer control, which is frequently employed in transition metal oxides. The so-called “Designer Crystals” enable observation and control of exotic but useful functional properties, that are unattainable in bulk crystals available in nature. Emergent quantum phenomena such as magnetoelectric coupling, Mottronics, and topological electronics have been shown for the artificial systems. Among them, atomic thickness dependents metal-insulator transition (MIT) is a one of the key topics for the atomic-scale electronics, which let us assess the low dimensional behavior of a material, which is typically intertwined with spin ordering in transition metal oxides.
