doped

Examples of doped 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.

• 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).
