): The energy difference between these bands. For a material like silicon , the bandgap is approximately 1.12 eV, allowing it to act as an insulator at absolute zero but conduct current as temperature increases. Intrinsic vs. Extrinsic Semiconductors
Pure forms of materials like silicon or germanium with no added impurities. Their conductivity is solely temperature-dependent. semiconductors a comprehensive guide pdf
Created through doping , the intentional introduction of impurities to enhance conductivity. ): The energy difference between these bands
