PbTe (Lead Telluride) pellets are a key material for physical vapor deposition (PVD) processes, such as thermal evaporation and electron-beam evaporation, to create high-quality thin films. PbTe is a narrow bandgap semiconductor commonly used in thermoelectric and infrared applications due to its excellent electrical and thermal properties.

Key Applications:

• Thermoelectric Devices: PbTe is widely used in thermoelectric generators and coolers due to its ability to efficiently convert heat to electricity and vice versa. It has a high thermoelectric figure of merit, especially in mid-temperature applications (200°C to 400°C).
• Infrared Detectors: PbTe’s narrow bandgap (~0.32 eV) allows it to detect infrared radiation in the mid-IR range (3-5 µm), making it ideal for IR detectors, infrared sensors, and thermal imaging devices.
• Optoelectronic Devices: PbTe is used in infrared light-emitting diodes (LEDs), lasers, and photodetectors for IR communication and imaging applications.
• Mid-Infrared Lasers: PbTe thin films are utilized in mid-IR laser diodes due to their excellent IR optical properties.

Features:

• Narrow Bandgap Semiconductor: PbTe has a bandgap of approximately 0.32 eV, which enables high sensitivity to infrared radiation in the 3-5 µm range.
• High Thermoelectric Efficiency: PbTe has excellent thermoelectric properties, making it suitable for energy conversion in both power generation and refrigeration applications.
• Good Thermal and Electrical Conductivity: PbTe exhibits strong thermal and electrical conductivity, essential for efficient thermoelectric devices and IR detection systems.
• Infrared Absorption: PbTe is highly effective at absorbing infrared light, particularly in the mid-IR region, making it ideal for infrared detectors and optoelectronic devices.
• Thin Film Deposition: PbTe can be deposited as a uniform thin film through evaporation techniques, ensuring high performance in electronic and optoelectronic applications.
