Overview of 99.99% P type Bismuth Telluride powder , Round N type Bi2Te3 target, 4N TeCl4 tellurium chloride tellurium tetrachloride
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.

Parameters of 99.99% P type Bismuth Telluride powder , Round N type Bi2Te3 target, 4N TeCl4 tellurium chloride tellurium tetrachloride
Bismuth Telluride (Bi2Te3), a promising material in the realm of thermoelectricity and optoelectronics, is often synthesized in various forms to cater to specific applications. The product you’ve mentioned consists of two distinct components: a high-purity P-type (positive charge carrier) Bismuth Telluride powder and a Round N-type (negative charge carrier) Bi2Te3 target.
The P-type Bismuth Telluride powder boasts an exceptional purity level of 99.99%. This indicates that the material has very low impurities, ensuring optimal performance in devices where high efficiency and minimal contamination are crucial. The purity grade of 4N (99.999%) signifies a superior level of purification, which contributes to better charge transport properties and minimized defects within the crystal structure.
The Round N-type Bi2Te3 target, on the other hand, is a solid form of the material, typically used for thin film deposition or as a starting point for further fabrication processes. Its round shape could be advantageous in certain manufacturing techniques, allowing for more uniform coverage or easier handling. The N-type doping creates an excess of electrons, making it suitable for applications requiring high electrical conductivity.
Tellurium Chloride (TeCl4), also known as tellurium tetrachloride, is an important precursor in the synthesis of Bismuth Telluride compounds. The 4N grade TeCl4 you’ve specified indicates a high purity level of 99.99% for this chemical compound. It is essential for obtaining high-quality Bi2Te3 powders and targets, as impurities can negatively impact the final product’s properties.
In summary, the combination of the 99.99% pure P-type Bismuth Telluride powder and the Round N-type Bi2Te3 target, both at a high purity standard, along with the use of 4N Tellurium Chloride, represents a high-quality material set for advanced electronic and photonic devices. These materials find applications in thermoelectric generators, solar cells, and optoelectronic devices due to their unique properties, such as high Seebeck coefficients and low thermal conductivity. The absence of a specific format suggests that these materials are tailored for custom orders or research purposes, where precise specifications are required.
