Semiconductor Electronics Materials, Devices and Simple Circuits — Syllabus & Topics

Topics covered in Semiconductor Electronics Materials, Devices and Simple Circuits for AP EAPCET Physics.

Topics in Semiconductor Electronics Materials, Devices and Simple Circuits

1

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
2

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
3

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
4

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
