K-Cell Series

High-Temperature K Cell (THKC-1300HI/THKC-1900HI)

高温Kセル

Features

  • Achieves a low degas feature.
  • Maintains the vacuum of 10-8Pa when heated to 1500℃ without evaporation material loaded. (Measured in the ultra-high vacuum chamber of EpiQuest.)
  • Enables accurate flux measurement due to low degas thereby achieving highly pure growth (Achieves better flux control compared with that obtained by an EB gun)
  • Can be used as an evaporation source for high melting point materials.
     (Example) metal epitaxial, oxide superconductor, etc.
