Kobayashi Group

About us

Kobayashi group investigates electronic structure of functional electronic materials using synchrotron radiation spectroscopy. Purposes of the research are to figure out the origin/mechanism of the novel quantum properties and to find fundamental indicators for material design.

Research subjects

  • Ferromagnetic semicondutor
  • Transition metal oxide
  • Metallic quantum well of strongly correlated oxide
  • Oxide heterostructure
  • Strongly correlated electron system

and other electronic materials.

Experimental Method

We study electronic structure of materials using synchrotron radiation spectroscopy.

  • Photoemissoion spectroscopy (PES)
  • X-ray absorption spectroscopy (XAS)
  • X-ray magnetic circular dichroism (XMCD)
  • Resonant inelastic x-ray scattering (RIXS)
  • Angle-resolved photoemission spectroscopy (ARPES)
  • X-ray absorption fine structure (XAFS)
  • Pulsed laser deposition (PLD) method for thin film growth
