This lecture by the instructor covers the importance of monodispersity and homogeneous composition in controlling nanocrystal properties. Topics include burst and delayed nucleation techniques, continuous monomer supply for size tuning, and the influence of factors like temperature, ligand steric hindrance, and chemical potential on size and shape control. The lecture also delves into the Wulff construction, ligand effects on surface energy, and the impact of seed crystalline phase symmetry on final nanocrystal shape.
