Applications of MgO single crystal substrates:

  • Substrate for high temperature superconducting film formation, such as YBCO film (filter used for communication and space observation)
  • Substrate for ferroelectric film formation, such as PZT film (infrared ray sensor used for thermometer and thermoregulator)
  • Substrate for diamond growth
  • Substrate for magnetic film formation (MRAM, TMR)
  • Target material for sputtering
