Lead is a classic low-temperature superconductor. High-purity lead thin films are essential for fabricating:
The superconducting transition temperature (Tc) and critical current are highly sensitive to impurities and film morphology, making target purity and process control paramount.
Lead chalcogenides (PbS, PbSe, PbTe) are important semiconductors for mid- and long-wavelength infrared detection. Sputtering from a high-purity lead target in a reactive sulfur, selenium, or tellurium atmosphere is one method to deposit these compound films for IR sensors, thermal imaging, and spectroscopic applications.
Lead is a soft, low-melting-point metal with specific handling requirements:
For lead intended for superconducting applications, trace impurity analysis is critical. We utilize Glow Discharge Mass Spectrometry (GDMS) or Inductively Coupled Plasma Mass Spectrometry (ICP-MS) to provide parts-per-billion (ppb) level quantification of elements like Fe, Cu, Ag, and Bi, which can severely degrade superconducting performance. This high-sensitivity certification differentiates our research-grade targets.
