Overview of GALLIUM TELLURIDE with hot CAS 12024-14-5
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.
Feature of GALLIUM TELLURIDE with hot CAS 12024-14-5
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.

Gallium Telluride (GaTe) is a fascinating and technologically significant compound that falls under the broader category of binary compounds, which consist of two elements combined in a fixed ratio. With the chemical formula GaTe, it is formed by the combination of gallium (Ga), a chemical element with atomic number 31 and symbol Gallium on the Periodic Table, and tellurium (Te), an element with atomic number 52 and represented by Te. Tellurium, known for its golden luster, is often found in combination with selenium or sulfur.
The discovery of gallium telluride dates back to the early 20th century when German chemists first synthesized it. It gained prominence due to its unique properties, particularly its semiconducting nature, which makes it an essential material in the electronics industry. Gallium Telluride is a wide-bandgap semiconductor, meaning it has a larger energy gap between its valence and conduction bands compared to other commonly used materials like silicon (Si). This property allows it to operate at higher temperatures without losing its electrical conductivity, making it suitable for applications where heat resistance is crucial.
One of the most notable uses of GaTe is in high-power infrared optoelectronics. Its transparency in the mid-infrared region makes it ideal for creating detectors, emitters, and modulators for infrared radiation. It is also employed in photovoltaic cells and solar concentrators, as its ability to absorb sunlight efficiently can be harnessed for converting light into electricity.
In addition to its electronic applications, gallium telluride has found applications in laser technology. Due to its direct bandgap, GaTe can be used to create high-power laser diodes and laser crystals, enabling the development of compact and efficient devices for various industries, including telecommunications and military applications.
Another area where GaTe shines is in thermoelectric materials. Thermoelectricity is the conversion of temperature differences into electrical power, and gallium telluride exhibits a relatively high figure of merit (ZT), which is a critical parameter for assessing a material’s thermoelectric efficiency. This property makes it an attractive candidate for waste heat recovery systems and portable power generators.
However, gallium telluride is not without challenges. The synthesis process can be complex and expensive due to the reactivity of both gallium and tellurium. Furthermore, the scarcity of tellurium as a raw material adds to the cost and environmental concerns. Research is ongoing to develop alternative methods and compositions that can address these issues while maintaining the desirable properties of gallium telluride.
In conclusion, gallium telluride, with its CAS number 12024-14-5, is a versatile and valuable material with a range of applications in the realms of electronics, optoelectronics, and thermoelectricity. Its unique properties make it a sought-after component in modern technologies, from infrared sensors to high-performance lasers. Despite its challenges, ongoing research and development continue to explore ways to optimize and expand its use, ensuring its relevance in the ever-evolving world of science and technology.
