CY2409 Lead Telluride (PbTe) Single Crystal Substrates

Lead Telluride Single Crystal Substrate Descriptions

Lead telluride (Phoebe) is a compound of lead and tellurium (PbTe); it is a narrow gap semiconductor. It occurs naturally as the mineral altaite. It is often alloyed with tin to make lead tin telluride, which is used as infrared detector material.

Each substrate is individually wrapped in soft, static-free foam to protect the material from mechanical damage and environmental contaminants during transit.

FAQs

Q1 How do I choose the right PbTe substrate for my application?

• Answer: The choice of PbTe substrate depends on the specific thermoelectric or semiconductor application. Factors such as crystal orientation, thickness, and size should be considered. For example, for thin-film deposition, a smoother surface may be required, while for power generation, the crystal's thermoelectric properties and size are more critical.

Q2 How should PbTe single crystal substrates be handled and stored?

• Answer: PbTe single crystal substrates should be handled with care to avoid contamination or damage to the crystal surface. It is important to store them in a clean, controlled environment, away from moisture or corrosive gases. Proper packaging and handling during transportation are essential to maintain the substrate's quality.

Q3 What are the typical challenges with PbTe single crystal substrates?

• Answer: One of the main challenges is the difficulty in growing high-quality PbTe crystals with consistent properties. The material's growth process must be carefully controlled to avoid defects that can impact its performance in thermoelectric and semiconductor applications. Additionally, PbTe's toxicity needs to be handled properly during manufacturing.
