Chalcogenide Materials Overview
Chalcogenide materials are compounds formed by combining one or more chalcogen elements—mainly sulfur (S), selenium (Se), or tellurium (Te)—with metals or metalloids. These materials are typically semiconductors, known for their unique electrical, optical, and phase change properties, and are widely used in advanced technologies.

Chalcogenide Material

Chalcogenides provided by ULPMAT:

  • Binary compounds: GeSe₂, Sb₂S₃, Cu₂Te
  • Ternary and multinary systems: Ge₂Sb₂Te₅ (GST), CuInSe₂, CuInGaSe₂ (CIGS)

Characteristics of Chalcogenides

  • Phase change capability: Reversible amorphous-to-crystalline transitions critical for non-volatile memories (e.g., PCM)
  • High refractive index and IR transparency: Suitable for infrared optics and photonic devices
  • Tunability: Electrical and optical properties are adjustable via doping and composition control
  • Low thermal conductivity: Ideal for thermoelectric devices
  • Excellent glass-forming ability: Usable in both bulk and thin film applications
  • Semiconductor process compatibility: Easily integrated into advanced electronics manufacturing

Applications of Chalcogenides

  • Phase-change memory (PCM): e.g., GeSbTe alloys for non-volatile memory (ReRAM, 3D XPoint)
  • Photonic and optical devices: Infrared lenses, waveguides, and photonic ICs
  • Thermoelectric materials: Bi₂Te₃ for waste heat recovery and temperature control
  • Photovoltaics: CIGS thin films for efficient solar energy conversion
  • Sensing & imaging: Used in gas sensors, infrared detectors, biomedical sensors
  • Glass & coatings: Specialty chalcogenide glass for mid- and far-infrared optics
