Indium III telluride, chemically denoted as In2Te3, is a ternary compound semiconductor composed of indium and tellurium. Unlike the binary InTe, In2Te3 features a more complex crystal structure and distinct electronic properties, making it suitable for a variety of specialized applications. It is known for its layered structure, which consists of stacked sheets of indium atoms sandwiched between tellurium atoms.
Features of Indium III Telluride (In2Te3) Powder
Crystal Structure: In2Te3 typically exhibits a layered hexagonal crystal structure (also known as a CdI2-type structure), which influences its anisotropic physical and electronic properties.
Semiconductor Properties: It is a p-type semiconductor with a bandgap that varies depending on synthesis conditions but generally falls within the range of narrow bandgap materials, making it suitable for optoelectronic applications.
Thermal and Electrical Conductivity: In2Te3 shows good electrical conductivity along the layers and lower conductivity perpendicular to the layers, which is beneficial for certain types of electronic devices.
Thermoelectric Performance: Like many telluride compounds, In2Te3 has been investigated for its thermoelectric properties, showing potential for waste heat recovery due to its combination of electrical conductivity and low thermal conductivity.
Chemical Stability: It demonstrates reasonable stability under ambient conditions, although it can react with oxidizing agents.
