germanium

Thân thiện

A scientist examines a sample of germanium under bright laboratory lights.

Definition

Noun: 1. A brittle, grayish-white, crystalline chemical element: Germanium is a metalloid element with semiconducting properties. It is chemically similar to silicon and is found in certain ores like germanite and argyrodite. Its primary historical use was in early transistors and semiconductor devices.

Usage Examples

• Noun:
  • Germanium is an element with atomic number 32 on the periodic table.
  • The purity of the germanium crystal is critical for its semiconductor performance.
  • Early solid-state electronics relied heavily on germanium transistors.

Advanced Usage

• Technical/Scientific Context: In materials science and electronics, "germanium" specifically refers to the element (symbol Ge) and its various allotropic forms (e.g., crystalline germanium, amorphous germanium) used in infrared optics, fiber optics, and as a substrate for other semiconductors.
  • The research focuses on doping germanium with gallium to alter its electrical properties.

Variants and Related Words

• Germanite (n): A rare copper-iron-germanium sulfide mineral, which is one of the commercial sources of germanium.
• Argyrodite (n): A silver-germanium sulfide mineral, historically important as the mineral in which germanium was first discovered.

Synonyms

• Element 32: Referring to its atomic number.
• Ge: Its chemical symbol (used primarily in scientific contexts).

Related Compounds and Terms

• Germanium dioxide (GeO₂): The primary oxide of germanium, used in the production of optical fibers and as a catalyst.
• Germanium transistor: An early type of transistor where germanium was the semiconductor material.
