Definition

Noun: * A semiconducting material is a substance, such as silicon or germanium, whose electrical conductivity is greater than that of an insulator but less than that of a metal. Its unique property is that its conductivity can be controlled and increased by factors like raising its temperature or introducing specific impurities.

Usage Examples

• Noun:
  • Silicon is the most important semiconducting material in the electronics industry.
  • The purity of the semiconducting material directly affects the performance of the transistor.
  • Researchers are developing new semiconducting materials for more efficient solar cells.

Advanced Usage

• "Doped semiconducting material": A semiconductor into which a small, controlled amount of an impurity has been introduced to modify its electrical properties.
  • The process of creating a p-n junction involves using both n-type and p-type doped semiconducting material.
• "Intrinsic semiconducting material": A pure semiconductor with no significant impurities, where electrical conduction is due to the thermal excitation of its own atoms.
  • At room temperature, an intrinsic semiconducting material has relatively low conductivity.

Variants and Related Words

• Semiconductor (n): The more common and general term for a semiconducting material or a device made from it.
  • The company is a leading manufacturer of semiconductor chips.
• Semiconductive (adj): Having the properties of a semiconductor.
  • The researcher studied the semiconductive properties of the new compound.

Synonyms

• Semiconductor: The direct and most frequent synonym.
• Solid-state material (in specific contexts): Often used when referring to the physical basis of electronic devices that use semiconductors.

Related Terms and Concepts

• Band gap: The energy difference in a semiconducting material between its valence band and conduction band, which determines its electrical properties.
• Doping: The intentional introduction of impurities into a semiconducting material to change its electrical conductivity.
• Transistor: A fundamental electronic device constructed from semiconducting material.

Noun

1. a substance as germanium or silicon whose electrical conductivity is intermediate between that of a metal and an insulator; its conductivity increases with temperature and in the presence of impurities
