PbS (Lead sulfide) Substrates
PbS, also known as Lead sulfide, is a inorganic compound and a wide bandgap semiconductor material that has been used for various applications, including infrared detectors and photovoltaics. PbS can be deposited onto various substrates, including glass, silicon, and quartz, to create a thin film for these applications. The electrical and optical properties of PbS make it an attractive material for use in optoelectronic devices. However, its toxicity and the need for specialized processing methods to deposit the material make it less commonly used compared to other semiconducting materials.
