Solid State — Physics So Pillai.pdf __link__

The heart of solid-state physics lies in explaining why some materials conduct electricity while others do not. Pillai transitions smoothly from classical Drude models to quantum mechanical band theory. He first presents the , where electrons are treated as a gas moving in a constant potential. While this model explains Ohm’s law and electrical conductivity, it fails to account for the existence of insulators and semiconductors.
