Description of Silver Telluride Ag2Te Puffer :

Silver telluride is a metallic compound with the formula AgTe. Similar to germanium telluride, it also belongs to the IV-VI group and has the properties of direct bandgap semiconductor materials.

The crystal structure of silver telluride is similar to that of silicon and germanium, both belonging to the cubic crystal system. In the crystal structure of silver telluride, each Ag atom is surrounded by four Te atoms, forming a tetrahedral structure. This structure is different from the crystal structure of silicon and germanium because they are direct bandgap semiconductors with high light absorption coefficients and light solid response.

The electronic properties of silver telluride are similar to those of germanium telluride and have direct bandgap properties and high electron mobility. Its bandgap energy is about 0.5-0.6 eV, which is identical to that of silicon and germanium. Because of its direct band gap properties, silver telluride has a wide range of applications in optoelectronic devices. In addition to its electronic properties, silver telluride has some unique physical properties. For example, its thermoelectric properties are similar to germanium telluride, with a higher Seebeck coefficient and resistivity. This allows it to convert heat energy into electricity and has good thermal stability. In addition, silver telluride also has some unique magnetic properties, such as magnetoresistive solid effect and magnetooptical effect.

A chemical that has the formula Ag2Te, silver telluride can be described as a chemical. It is stable in the air but insoluble in water or potassium cyanide.

Production Method of Silver Telluride Ag2Te Powder：

Solid phase reaction

Solid state reaction is a standard method for preparing silver telluride. The technique is to mix silver powder and tellurium powder according to a particular proportion and then react at high temperatures. During the reaction, atoms of silver and tellurium diffuse with each other to form Ag-Te solid solutions. With the progress of the reaction, the composition of Ag-Te reliable solution gradually deviates from the stoichiometric ratio, and finally, AgTe compounds are formed. The advantages of the solid-state reaction method are a simple preparation process and low cost, which is suitable for large-scale production. However, the disadvantage of this method is that the purity of the product could be higher, and further purification is required.

Vapor deposition method

Vapor deposition is a method for preparing high-performance silver telluride. The technique is to react with the vapor of silver and tellurium at high temperatures to form AgTe compounds. The advantage of vapor deposition is that high-purity AgTe compounds can be prepared, and the resulting products have fewer crystal structures and defects and better properties. However, the disadvantage of this method is that the preparation conditions are high, the cost is high, and it is not suitable for large-scale production.

Sol-gel method

The sol-gel method is a standard method for preparing nanomaterials. The technique is to dissolve alcohols or inorganic salts of silver and tellurium in a solvent to form a uniform sol. Then, through heating or the action of a catalyst, the solvent in the sol evaporates to form a gel. After the gel is dried and heat treated, AgTe compounds are obtained. The advantage of the sol-gel method is that AgTe compounds with high purity and high performance can be prepared, the crystal structure and defects of the obtained products are less, and the properties are better. However, the disadvantage of this method is that it is easy to introduce impurities in the preparation process, the preparation conditions are higher, and the cost is higher.

Chemical vapor deposition

Chemical vapor deposition (CVD) is a method for preparing high-performance thin film materials. The technique involves electrolysis of oxides or halides of silver and tellurium in an electrolyte to form AgTe compounds by electrochemical reaction. The advantage of chemical vapor deposition is that AgTe compounds with high purity and high performance can be prepared, and the resulting products have fewer crystal structures and defects and better properties. However, the disadvantage of this method is that the preparation conditions are high, the cost is high, and it is not suitable for large-scale production.

Electrolytic method

Electrolysis is a method for preparing high-performance metal compounds. The technique involves electrolysis of oxides or halides of silver and tellurium in an electrolyte to form AgTe compounds by electrochemical reaction. The advantage of electrolysis is that AgTe compounds with high purity and high performance can be prepared, and the resulting products have fewer crystal structures and defects and better properties. However, the disadvantage of this method is that the preparation conditions are high, the cost is high, and it is not suitable for large-scale production.

Field of thermoelectric conversion devices

Silver telluride is an excellent thermoelectric material with high thermoelectric conversion efficiency. It has a high Seebeck coefficient of about 400 μV/K, which allows it to convert heat energy into electricity. Therefore, silver telluride is widely used in the manufacture of thermoelectric conversion devices, such as thermoelectric generators, thermoelectric refrigerators, and thermoelectric sensors. These thermoelectric conversion devices have many applications in energy, environmental protection, and medical fields.

Solar cell field

Silver telluride has been widely used in solar cells due to its direct band gap properties, high transmittance, and light solid absorption capacity. Compared with traditional silicon-based solar cells, silver telluride solar cells have a higher light absorption coefficient and a more comprehensive spectral response range. In addition, due to their high-temperature stability and high electron mobility, silver telluride solar cells perform better in high-temperature and high-humidity environments. Therefore, silver telluride solar cells are widely used in photovoltaic power generation.
