Description |
It starts with talking about electrons in full bands, then it goes back to solid bodies and how energy levels are filled in them. It then talks about the effect of energy bands on conductivity. It also talks about half-full energy levels in solid materials and different energy structures in conductors, semi-conductors, and insulators. |
Mental Challenge |
What is the relation between conductivity and energy structure of materials? |
Quizzes and Activities |
Activity: Sketch schematics of atoms for conductors, semi-conductors, and insulators |
