Overview of BISMUTH TELLURIDE with high efficiency CAS 1304-82-1
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 BISMUTH TELLURIDE with high efficiency CAS 1304-82-1
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.

Parameters of BISMUTH TELLURIDE with high efficiency CAS 1304-82-1
Bismuth Telluride (Bi2Te3), also known as BiTe or Bismuth-Telluride, is a fascinating material that has garnered significant attention in the scientific community due to its exceptional properties, particularly in the realm of thermoelectric materials. With the chemical formula Bi2Te3 and a CAS number of 1304-82-1, this compound holds promise for various applications, including waste heat recovery, electronic devices, and next-generation energy conversion technologies.
Tellurium, a rare element, combines with bismuth to form a semiconductor alloy that exhibits unique thermoelectric properties. The efficiency of Bi2Te3 lies in its ability to convert temperature differences into electrical power without the need for external mechanical work. This process, known as the Seebeck effect, makes it particularly appealing for waste heat recovery systems, where it can convert the otherwise wasted thermal energy into usable electricity.
One of the key factors contributing to Bi2Te3’s high efficiency is its high thermoelectric figure of merit (ZT), which is a dimensionless parameter that quantifies a material’s thermoelectric performance. A higher ZT value indicates better efficiency, and Bi2Te3 has shown ZT values approaching 2.5 at room temperature, surpassing many conventional thermoelectric materials. This remarkable performance is primarily due to its low lattice thermal conductivity and relatively high electrical conductivity, which create an ideal balance for efficient energy conversion.
Moreover, Bi2Te3’s band structure, characterized by a narrow bandgap, allows for efficient charge carrier transport. The combination of p-type and n-type semiconductors in a single crystal structure enhances the Seebeck coefficient, further boosting its thermoelectric efficiency. Researchers have been working on optimizing the material’s composition and nanostructuring techniques to improve its performance, such as by incorporating nanostructured elements like quantum dots or nanowires.
Another aspect that sets Bi2Te3 apart is its compatibility with thin-film fabrication methods, which enable integration into flexible and lightweight devices. This is crucial for applications like wearable electronics and microscale power generators, where size and weight play a critical role.
However, despite its promising potential, Bi2Te3 faces challenges in large-scale commercialization. The scarcity of tellurium, a key component, and the complex synthesis process can drive up costs. Additionally, improving the material’s stability under operating conditions and developing scalable production techniques remain ongoing research efforts.
In conclusion, Bismuth Telluride with its high efficiency CAS number 1304-82-1 is a game-changer in the field of thermoelectrics. Its exceptional thermoelectric properties, coupled with the possibility of miniaturization and integration, make it a valuable candidate for numerous applications, from power generation to waste heat recovery. Ongoing research and advancements in material science will continue to refine and optimize this material, paving the way for more sustainable and efficient energy solutions in the future.
