Thin Films: Deposition and Growth

This lecture covers the preparation of thin films in inorganic and organic electronics, discussing vapor phase and solution phase deposition processes. It explains the growth mechanisms, such as island growth and layer-by-layer growth, and specific considerations for organic thin film growth. The lecture also delves into the surface migration of clusters, nucleation rate, and the effects of surface energy on film growth. Various techniques for organic thin film deposition, including vacuum thermal evaporation and solution phase deposition by spin coating, dip coating, doctor blading, and slot-die casting, are explored. Additionally, the lecture touches on crystal growth alignment and the application of solvent vapor annealing to enhance grain size.
