Class 12 Physics Semiconductor Electronics Classification of semiconductors

Classification of semiconductors

The semiconductors can be classified into Elementary type semiconductor and compound type semiconductor

  • Elementary type semiconductor – These type of semiconductors are available in natural form like Silicon (Si) and germanium (Ge)
  • Compound type semiconductor – When semiconductors are made by compounding the metals, we get compound type semiconductor. They can be further classified into
    • Inorganic semiconductors like CdS, GaAs etc
    • Organic semiconductors like Antracene, doped pthalocyanines
    • Organic polymers – Polypyrole, polyaniline, polythiophene
