Zinc Telluride

Zinc Telluride Powder Overview 

Zinc telluride powder is a high-purity II-VI compound semiconductor material with the chemical formula ZnTe. This product appears as a dark gray to brownish-black crystalline powder featuring a sphalerite cubic crystal structure. It is a direct-bandgap semiconductor with a bandgap width of approximately 2.26 eV. It combines outstanding infrared optical properties, thermoelectric conversion potential, and highly efficient photoelectric response capabilities, making it a key foundational material for fabricating infrared photodetectors, high-efficiency solar cells, and thermoelectric materials.

We offer high-quality zinc telluride powder in multiple purity grades, particle size specifications, and surface treatment options. Contact us for samples.

Applications of Zinc Telluride Powder

Infrared Photodetection and Devices: Core functional material for manufacturing high-performance infrared photodetectors, light-emitting diodes, and lasers.
High-efficiency thin-film solar cells: Serves as an absorber layer material in novel thin-film solar cells like cadmium telluride or copper zinc tin selenide, enhancing photovoltaic conversion efficiency.
Thermoelectric energy conversion materials: Functions as a thermoelectric material in modules that directly convert waste heat into electricity, enabling energy recovery and utilization.

FAQs

Q1: What are the primary characteristics of ZnTe powder?
A1: Its core properties—direct bandgap, infrared sensitivity, and excellent thermoelectric performance—make it highly valuable in infrared detection and new energy applications.

Q2: How should powder purity be selected?
A2: Selection depends on the application. For high-performance semiconductor devices, 99.99% (4N) purity or higher is recommended; certain thermoelectric or additive applications may require tailored purity levels.

Q3: How should the product be stored?
A3: This product is sensitive to air and moisture. It must be stored in a tightly sealed container under dry, inert gas protection to prevent oxidation and degradation.

Q4: What are the main differences between ZnTe powder and ZnSe powder?
A4: The bandgap and application wavelength bands differ. ZnTe has a narrower bandgap, focusing on near-infrared detection and photovoltaics; ZnSe has a wider bandgap with superior infrared transmittance, emphasizing mid-to-far-infrared optics and lasers.
