Revision Notes — Semiconductor Electronics Materials, Devices and Simple Circuits
Key concepts, formulas, and definitions from Semiconductor Electronics Materials, Devices and Simple Circuits for CUET (UG) Physics preparation.
Key Topics to Revise
Classification of Materials and Energy Band Theory
- Materials are classified into conductors, semiconductors, and insulators based on their energy band structure
- Valence band contains valence electrons that don't contribute to conduction
- Conduction band contains free electrons that contribute to electrical conduction
Intrinsic and Extrinsic Semiconductors
- Intrinsic semiconductor: Pure semiconductor with ne = nh = ni
- Conductivity increases with temperature due to thermal generation of electron-hole pairs
- n-type: Doped with pentavalent impurities (As, P, Sb) - electrons are majority carriers
p-n Junction and Diode Characteristics
- p-n junction forms depletion layer with immobile ions
- Built-in potential barrier: ~0.3V for Ge, ~0.7V for Si
- Forward bias: p-side positive, reduces barrier, high current
Rectifiers and Applications
- Rectification converts AC to pulsating DC using diode's unidirectional property
- Half-wave rectifier uses one diode, rectifies only one half of AC cycle
- Full-wave rectifier uses two diodes with center-tapped transformer
