Moderate

The process of adding controlled impurities to a semiconductor is known as _. The amount of impurity added to an intrinsic (pure) semiconductor varies its level of conductivity.

Correct answer: D. Doping

  • A. Crystallography
  • B. Rectification
  • C. Intrinsic defects
  • D. Doping

Explanation

Doping. The conductivity of semiconductors may easily be modified by introducing impurities into their crystal lattice.

About Physics of Solids

Solids are compared through crystal structure, amorphous arrangement, elasticity, plastic deformation, stress, strain and Young’s modulus. Electrical behavior depends on available charge carriers and band structure, so conductors, insulators and semiconductors must be distinguished from mechanical properties such as strength, stiffness and brittleness.
