Abstract:

Nanomanufacturing has aroused rising research interest due to the various applications in electronics, catalysts, and batteries, and nanofabrication methods for fabricating materials with atomic-level control are becoming increasingly important. Atomic layer deposition (ALD) is a vapor-based method that provides excellent capabilities for depositing ultrathin solid films, nanoparticles and other nanoscale materials. Based on sequential, self-limiting vapor-surface reactions, ALD has become a popular nanofabrication tool because it provides exceptional conformality, thickness control at the angstrom level, and high-quality pinhole free films.[1] In this talk, I will discuss the chemical principal and mechanisms that enable selective atomic layer deposition, which is gaining rapidly growing interest and has unlocked attractive avenues for the development of novel nanostructures by depositing atoms at desired surface locations.[2] It has found versatile applications in semiconductor industry and beyond.[3] I will also show that atomic level processes enabled functional layers and encapsulation techniques. Various applications ranging from flexible displays to energetic materials in power batteries will be discussed. [4] For future nanomanufacturing, ALD is still evolving to expand its abilities as an enabling technique, providing a window of opportunity for large scale atoms integration.
