InP Wafer

InP wafers are indium and phosphorus compounds. They are single crystals made using a specific LEC technique. They have a stable structure and are silver in color with the chemical formula InP.

Applications and Fields
InP is an important III-V compound and semiconductor material with high electron mobility, good radiation stability, and a large bandgap. InP has particular advantages in the following two applications.
  1. Photonics: Emission and detection capabilities at wavelengths greater than 1000 nm;
  2. Radio Frequency:High speed and low noise performance in high frequency RF applications. InP is the first choice in performance-driven niche markets such as communication, radar, test equipment, and radiation measurement.
