PbS Crystals

Description

PbS Crystals (Lead Sulfide)

PbS is a narrow bandgap semiconductor with exceptional optical, electronic, and thermoelectric properties. Known for its strong absorption in the infrared spectrum and high carrier mobility, PbS is widely used in optoelectronics, thermoelectric devices, and advanced quantum materials research. Our PbS crystals are synthesized using the Chemical Vapor Transport (CVT) method to ensure high purity, precise stoichiometry, and superior crystallinity for advanced research and industrial applications.
