This lecture covers the different growth modes in film growth, including 2D layer-by-layer mode and 3D island mode, as well as the crystal structure of films. It discusses the stability of film-substrate interfaces, the deposition of Ti on SiO2, and the determination of whether a film will be amorphous, polycrystalline, or monocrystalline based on the materials used. The lecture also introduces Thornton's zone model for sputtering of metals, explaining the zones and their effects on film structure.
