This lecture discusses the unique properties of van der Waals materials, focusing on 2D crystals with strong in-plane bonds and weak interlayer coupling. It covers the exfoliation process, dimensionality effects, crystal structures, band properties, lattice vibrations, and stacking configurations. The instructor explores the impact of layer sequencing, lattice vibrations, band structures, spin-orbit interactions, and the transition from spintronics to valleytronics. Additionally, the lecture delves into the functional properties of transition metal dichalcogenides, the effects of parallel/anti-parallel stacking, and the significance of Moiré patterns and strain modulation in 2D materials.
