Tellurium (Te) pellets are used as evaporation material in physical vapor deposition (PVD) techniques, including thermal evaporation and electron-beam evaporation. Tellurium thin films are valued for their applications in thermoelectric devices, phase-change memory (PCM), and semiconductor technology due to their unique electrical and optical properties.

Key Applications:

• Thermoelectric Devices: Tellurium is a key component in thermoelectric materials like bismuth telluride (Bi2Te3) and lead telluride (PbTe), which convert temperature differences into electrical voltage, used in cooling systems and power generation.
• Phase-Change Memory (PCM): Tellurium is used in phase-change materials (PCM) such as GeTe and GST (Ge-Sb-Te alloys) for data storage, offering fast read-write speeds and high durability in memory devices.
• Infrared Optics: Tellurium-based compounds, such as cadmium telluride (CdTe), are used in IR detectors, imaging, and optical coatings due to their infrared transparency and high refractive index.
• Semiconductors: Tellurium is used in semiconductor materials for infrared sensors, photovoltaics, and quantum dots.
• Photovoltaics: Tellurium plays a crucial role in cadmium telluride (CdTe) solar cells, providing a cost-effective, high-efficiency alternative for thin-film solar energy conversion.

Features:

• High Thermoelectric Efficiency: Tellurium-based materials, like Bi2Te3, are widely recognized for their superior thermoelectric performance, essential for thermoelectric cooling and power generation.
• Infrared Transparency: Tellurium compounds exhibit transparency in the infrared spectrum, which makes them useful for IR optics and imaging devices.
• Phase-Change Properties: Tellurium has excellent phase-change properties, which enable its application in PCM for non-volatile memory storage.
• High Purity: Tellurium used in evaporation is typically of high purity (≥ 99.99%), ensuring uniformity and high-quality thin film deposition.
• Stable Evaporation: Tellurium can be evaporated with thermal and electron-beam techniques, providing consistent deposition rates for thin films.
