How Does Boundary Scattering Affect Electrical Conductivity?
In bulk materials, electrons primarily scatter due to impurities and phonons. However, in nanoscale materials, boundary scattering can dominate. When electrons encounter the boundaries of a nanostructure, such as a [nanowire]() or thin film, their paths are deflected, leading to increased [resistance](). This is particularly important in devices like [transistors]() and [interconnects]() in integrated circuits, where minimizing electrical resistance is crucial for performance and energy efficiency.
