Laboratory for Condensed Matter (LSC)
in the Photon Science Division
The research focusses on condensed matter and materials science using synchrotron radiation. For this we use the whole range of spectroscopy, imaging and diffraction techniques.
Current Highlights and News
Synchrotron X-ray diffraction sheds light on laser-induced local recrystallization .
Experiments at the Swiss Light Source SLS help resolve a long-standing debate surrounding metal 3D laser printing.
Strontium titanate is a wide band gap semiconductor. Its surface can be rendered conductive by a mild annealing in vacuum. The present study reveals that by deposition of less than a monolayer of non-volatile organic molecules such as tetracyanoquinodimethane (TCNQ) this conductivity can be completely turned off. In view of the small size of TCNQ (ca. 1 nm) this could allow new pathways toward oxide-based electronics.
