Energy Gap Semiconductor Presentation

Introduction to Energy Gap Semiconductors
Energy gap semiconductors are materials with a moderate energy gap between their valence and conduction bands. The energy gap determines the ability of a semiconductor to conduct electricity. Examples of energy gap semiconductors include silicon (Si), germanium (Ge), and gallium arsenide (GaAs).	Image Source

Band Structure of Energy Gap Semiconductors
Energy gap semiconductors have a valence band filled with electrons and a conduction band empty or partially filled with electrons. The energy gap between the valence and conduction bands allows for the controlled flow of electrons. The size of the energy gap determines the conductivity properties of the semiconductor.

Types of Energy Gap Semiconductors
Intrinsic semiconductors have a pure crystal structure and exhibit limited conductivity at room temperature. Extrinsic semiconductors are doped with impurities to enhance conductivity. N-type semiconductors are doped with elements that provide extra electrons, making it easier for current flow.	Image Source
