Extensible and flexible UHV ultra low temperature bob体育中心
Capable of having near-field/Raman spectroscopy

VT UHV bob体育中心

This system is equipped with newly developed cryostat and utilized for new applications such as near field observation or Raman spectroscopy by using STM or the latest low temperature bob体育中心 with AFM function.


  • bob体育中心 measurement down to 3.0 K using newly developed cryostat
  • Flexible structure capable of various options such as optical lenses, depositions at observation point and additional probes.


  • Ultra low temperature STM, Inelastic tunneling spectroscopy (IETS)
  • Application to various AFM functions (MFM, KFM, SCM etc.)
  • Photoexcitation STM, AFM measurement
  • Ultra low temperature high resolution light emission induced by tunneling current, Tip-enhanced Raman spectroscopy
  • In situ deposition, Adsorption of atoms, molecules
