End Stations for Condensed Matter/Surface Science Studies - Soft X-ray, VUV & IR
Photoabsorption and Photodesorption End Station
Beamline : BL20A1 (HSGM)
Contact : J. M. Chen, ext. 7115, jmchen@nsrrc.org.tw

  Area of Research  
  The measuring techniques cover XANES in total electron yield and total X-ray fluorescence yield modes, PSD, XPS, and AES. The end station is intended for studying condensed phase photochemistry and electronic structures of new materials. The research areas include state-selective desorption dynamics of molecular adsorbates on surface following core-level excitation, relaxation dynamics of core-excited molecules, synchrotron radiation induced surface photochemistry, and electronic structure of high-Tc superconductors and magnetic materials.
