Overview of Professional High Quality TUNGSTEN SELENIDE CAS 12067-46-8 At Competitive
Telluride and selenide compounds play a significant role in the field of semiconductors, particularly in the development of advanced electronic and optoelectronic devices. These materials belong to the chalcogenide family, characterized by their ability to form compounds with elements from groups IV-VI in the periodic table.
Tellurides: Compounds containing tellurium (Te) as the chalcogen. Examples include cadmium telluride (CdTe), mercury telluride (HgTe), and zinc telluride (ZnTe). These materials have found applications in solar cells, infrared detectors, and high-speed electronics due to their tunable bandgap, high electron mobility, and good thermal stability.
Selenides: Similar to tellurides, but with selenium (Se) replacing tellurium. Notable examples are cadmium selenide (CdSe), gallium selenide (GaSe), and zinc selenide (ZnSe). Selenide compounds are widely used in light-emitting diodes (LEDs), laser diodes, and solar cells due to their direct bandgap properties and efficient light absorption/emission capabilities.

Direct Bandgap: Many telluride and selenide semiconductors have direct bandgaps, which facilitate efficient light emission and absorption processes. This makes them suitable for optoelectronic applications such as LEDs and lasers.
Tunable Bandgap: The bandgap of these materials can be adjusted by alloying or altering the composition (e.g., CdSe to CdTe), enabling customization for specific device requirements across a wide spectrum of wavelengths.
High Electron Mobility: Materials like HgCdTe exhibit high electron mobility, which is crucial for high-speed electronic devices and low-noise detector applications.
Thermal Stability: Some tellurides and selenides, like ZnTe and ZnSe, demonstrate good thermal stability, making them suitable for high-temperature operation and processing.
Non-Toxic Alternatives: With increasing environmental concerns, there’s a push towards exploring less toxic alternatives to commonly used semiconductors. For instance, Cd-based tellurides and selenides are being replaced or combined with less toxic elements like Mg or Mn in some applications.
