Fabrication Extended: Bottom-Up Methods

This lecture covers the fabrication of nanoparticles through gas, vapor, and liquid phase methods, such as spray pyrolysis and solvothermal reactions. It also explores the challenges in producing carbon nanotubes and nanowires, emphasizing the importance of controlling growth direction and diameter. The instructor discusses the VLS growth process for nanowires and the catalyzed reaction for graphene production, including transfer techniques. The lecture concludes with a comparison of bottom-up and top-down fabrication methods, highlighting the advantages and challenges of each approach.
