Pooljuhtkristalli
Pooljuhtkristalli, also known as lead telluride (PbTe), is a semiconductor material with a narrow bandgap, making it suitable for infrared detection and thermoelectric applications. It is a binary compound consisting of lead (Pb) and tellurium (Te) elements. Pooljuhtkristalli has a cubic crystal structure and is typically grown using techniques such as Bridgman-Stockbarger or zone melting methods. Its high electron mobility and low lattice thermal conductivity make it an attractive material for thermoelectric devices, which convert heat into electrical energy. Additionally, its narrow bandgap allows it to absorb infrared radiation, making it useful in infrared detectors and imaging systems. However, the toxicity of lead poses challenges in its handling and disposal, necessitating careful consideration in its application.
