Surface Energy and Semiconductor Nanostructures

This lecture covers the surface energy of various materials like C, Si, and Ge, the equilibrium crystal shape of Si, and the anisotropy of surface energy for Si. It also discusses the reconstruction of semiconductor surfaces, band schemes of n-doped semiconductors, and the role of surfaces in determining the electrical properties of semiconductors. The lecture further explores the deactivation of donors in silicon nanostructures and the impact of dopants in nanostructures compared to bulk materials.
