In this session, Formation of energy bands, classification of solids based on Energy band diagram, Meaning of conduction band, valence band, energy gap is discussed. Intrinsic semiconductors and extrinsic semiconductors are introduced. At the end, direct band gap semiconductors and indirect band gap semiconductors are compared. 2020-09-22T00:00:00Z
