Phosphorus Compounds Overview
Phosphorus compounds are III-V and II-V semiconductors that combine Group V elements (phosphorus (P), arsenic (As), or antimony (Sb)) with metals or metalloids like gallium (Ga), indium (In), or aluminum (Al). These materials—such as GaP, InAs, and InSb—offer exceptional optoelectronic and electronic properties vital to high-performance devices.

 

Properties of Phosphorus Compounds:

  • Direct bandgap: enables efficient light emission and absorption (e.g., GaAs, InP, InSb)
  • High electron mobility: ideal for high-speed, low-power electronics
  • Infrared sensitivity: essential for infrared detectors and thermal imaging
  • Thermoelectric properties: antimonides offer excellent thermoelectric performance
  • Stability & conductivity: transition metal phosphides exhibit good catalytic and conductive behavior

Applications of Phosphorus Compounds:

  • Optoelectronics: lasers, LEDs, photodetectors, transceivers (InP, GaAs)
  • High-frequency electronics: RF amplifiers and microwave devices (GaAs, InP)
  • Infrared sensing: used in night vision, spectroscopy, thermal imaging (InSb, GaSb)
  • Solar energy: efficient III-V solar cells (e.g., GaAs, InGaP)
  • Thermoelectrics: thermal energy conversion (InSb, GaSb)
  • Catalysis & energy storage: transition metal phosphides for HER/OER, batteries
