Description of Antimony Telluride sb2Te3 powder：

Chemical formula of antimony telluride: Sb2TE3.Molecular Weight 626.30.Gray Solid.Melting Point 639.Relative Density 6.5018. In nitric acids, dissolve. Antimony Telluride, or covalent or ionic bonds, can be dissolved in nitric acid.

Telluride is similar to other alveolar-sulfide layered antimony materials, a grayish crystalline solid with a multilayered structure. Two atomic antimony and three atomic protein sheets form the layer. The weak van der Waals force holds it together. The topological insulator is also used. It has thickness-dependent physical properties.

A rhomboid crystal structure is found in Sb2Te3. The crystal material is composed of five covalently bound atoms. These sheets form five bits thick (in order Te-Sb–Te–Te) and hold the plates together by Van der Waals attraction. Because of its lamellar shape and weak interlamellar force, bulk telluride is easily mechanically separated to remove the monolayers. Sb2Te's semiconductor properties include separating monolayers from antimony and bismuth. You can convert it to N-type or P-type semiconductors using the right dopants.

How does Antimony Telluride SB2Te3 powder be made?

Direct synthesis

Direct synthesis is a commonly used method for producing antimony telluride, which directly reacts with antimony and telluride at high temperatures to obtain antimony telluride. The specific steps are as follows:

The higher-purity antimony and tellurium elements are prepared; antimony is usually present in block or particle form, and tellurium is generally present in powder form.

Place the antimony block or particle and tellurium powder into the quartz tube, ensuring the ends are closed.

The quartz tube is placed in a heating furnace and heated to the appropriate temperature (usually 600-800 ° C).

The high temperature is maintained for some time (e.g., several hours) to allow the antimony and tellurium to react fully.

After the reaction, the quartz tube is removed, cooled, and opened, and the resulting antimony telluride crystals can be seen.

The advantages of direct synthesis are simple operation and easy availability of raw materials. However, it should be noted that the purity of antimony telluride obtained by this method may need to be higher, and further purification is necessary. In addition, the direct synthesis method has a higher cost and is unsuitable for mass production.

Electrolysis

Electrolysis is a method of preparing compounds by electrolysis of a solution, which can be used to produce high-purity antimony telluride. The specific steps are as follows:

An appropriate amount of antimony salts (such as antimony nitrate) and tellurium salts (such as tellurium chloride) are dissolved in a solvent (such as water) to obtain a mixed solution.

The mixture is poured into the cell, and a voltage is applied to both electrodes.

During electrolysis, antimony and tellurium ions are reduced to antimony and tellurium on the anode and deposited on the cathode to form antimony telluride.

The antimony telluride deposited on the cathode is collected for cleaning and drying.

The advantage of electrolysis is that high-purity antimony telluride can be prepared, and the cost is relatively low, which is suitable for large-scale production. In addition, antimony telluride can be controlled by electrolysis by adjusting the solution concentration and electrolytic conditions. However, it should be noted that the electrolysis method requires electrolytic equipment, and the operation is more complicated.

Application of Antimony Telluride sb2Te3 powder：

Semiconductor device

As an excellent semiconductor material, antimony telluride is widely used to manufacture various semiconductor devices, such as diodes, transistors, and integrated circuits.

In terms of diodes, antimony telluride can be used to make Schottky diodes, which have advantages such as low reverse leakage current, high switching speed, and low power consumption, so they have a wide range of applications in high-frequency and high-temperature environments. In addition, the antimony telluride diode also has the advantages of short reverse recovery time and low junction capacitance, which makes it widely used in high-speed switching power supplies, solar cells, and other fields.

On the transistor side, antimony telluride can make field-effect transistors (FETs), which have advantages such as low noise, high transconductance, and high-frequency characteristics. Due to the adjustable band gap of antimony telluride, its electrical properties can be optimized by changing the material composition, resulting in higher switching speeds and lower power consumption. Therefore, antimony telluride-based FETs have a wide range of applications in high-speed logic circuits, radio frequency (RF), and microwaves.

In terms of integrated circuits, antimony telluride can be used to manufacture high-speed and low-power integrated circuits because of its advantages of high mobility and low power consumption. In addition, due to the adjustable band gap of antimony telluride, its electrical properties can also be optimized by changing the material composition, allowing for a broader range of circuit designs and higher performance. Therefore, antimony telluride has many applications in microelectronics and nanoelectronics.

Infrared detector
