Examples of doping in the following topics:

  • Semiconductors

    • While insulating materials may be doped to become semiconductors, intrinsic semiconductors can also be doped, resulting in an extrinsic semiconductor.
    • Lightly and moderately doped semiconductors are referred to as extrinsic.
    • Doping atom usually have one more valence electron than one type of the host atoms.
    • The purpose of p-type doping is to create an abundance of holes.
    • After the material has been doped with phosphorus, an extra electron is present.
  • Doping: Connectivity of Semiconductors

    • The process of adding substances to a pure semiconductor for the purposes of modulating its electrical properties is known as doping.
    • Semiconductors are doped to generate either a surplus or a deficiency in valence electrons.
    • Doping provides a way to modulate the properties of semiconductors that have broad applications in daily life.
    • Doping a pure silicon semiconductor with the group V dopant arsenic creates a surplus of conductive electrons.
    • Examine the method of doping a pure semiconductor in order to increase its electrical conductivity.
  • Branches and Subdisciplines of Biology

    • A scan of news headlines—whether reporting on immunizations, a newly discovered species, sports doping, or a genetically-modified food—demonstrates the way biology is active in and important to our everyday world.
  • Repetition and Parallelism

    • "Today's students can put dope in their veins or hope in their brains.
  • Trihalides: Boron-Halogen Compounds

    • The electronics industry uses boron tribromide as a boron source in pre-deposition processes for doping in the manufacture of semiconductors.
  • Titanium, Chromium, and Manganese

    • Recall the beneficial physical characteristics that titanium, chromium, and manganese impart when doped into steel.
  • Molecular Crystals

    • Conductivity of molecular solids can be induced by "doping" fullerenes (e.g., C60).
