Germanium Telluride

Germanium Telluride powder is a dark gray or black powder with the chemical formula GeTe. It has specific physicochemical properties and has important applications in electronic devices, phase change storage, thermoelectric materials, infrared detection and other fields.

Properties

Chemical formula: GeTe

Molecular weight: 185.21

Appearance: Usually in the form of dark gray or black powder, with a certain metallic luster. Its color and luster come from its crystal structure and chemical bonding properties, which make its reflection and absorption of light show a specific performance.

Density: approx. 6.24 g/cm³.

Stability: It has a certain chemical stability at room temperature and pressure, but under certain conditions such as high temperature, strong oxidation or strong acid and alkali, its chemical stability will be reduced and it is prone to chemical reaction. For example, when heated to a certain temperature in air, it may undergo oxidation reaction with oxygen to produce the corresponding oxides.

Oxidizing and Reducing Properties: Germanium and tellurium elements in Germanium Telluride have certain oxidizing and reducing properties, which makes it able to participate in a variety of redox reactions. It can react with a number of metals, non-metals or compounds to produce the corresponding germanium compounds, tellurium compounds or other complex compounds, a property that provides the basis for its application in materials synthesis and chemical reactions.

Reaction with acids and bases: Germanium Telluride can react with some strong acids and bases to form corresponding salts and other compounds. Therefore, it is necessary to avoid contact with acids, bases and other corrosive substances during handling and use to prevent dangerous reactions, and this also provides a reaction pathway for its use in some specific chemical treatment processes.

Applications

Electronic devices: It is an important semiconductor material, which can be used to prepare electronic devices such as thin-film transistors, memories and logic circuits. Its unique electrical properties, such as suitable forbidden band width, high carrier mobility, etc., can meet the demand for high-performance materials for modern electronic devices, and help to realize the miniaturization, high-speed and low power consumption of electronic devices.

Phase Change Storage: In phase change memory, Germanium Telluride, as an important component of phase change materials, is able to undergo rapid crystalline and amorphous transitions at different temperatures and electric fields, thus realizing data storage and reading. This storage technology based on the phase transition principle has the advantages of fast read/write speed, high storage density and non-volatility, which is one of the important development directions of next-generation storage technology.

Thermoelectric material: Germanium Telluride has certain thermoelectric properties, and can be used as thermoelectric material in the fields of temperature difference power generation and thermoelectric refrigeration. It can convert thermal energy into electrical energy or use electrical energy to realize the cooling effect, which has potential application value in energy recovery, waste heat utilization and small-scale refrigeration equipment, etc., and helps to improve the efficiency of energy utilization and realize the development of green energy.

Infrared detection: Germanium Telluride can be used to manufacture infrared detectors due to its good absorption and response characteristics to infrared light. In military, security, environmental monitoring and other fields, infrared detectors can realize non-contact detection and imaging of target objects, with good concealment, strong anti-interference ability and other advantages, which is of great significance to safeguard national security and social stability.
