    • Low-energy surface vibration measurements on the alpha-quartz (0001) surface 

      Luneng, Jenny Louise (The University of Bergen, 2011)
      Despite the enormous range of usages, only little is known about the dynamic and structural properties of quartz (SiO2) surfaces on the atomic scale. The main reason for this is probably that quartz is an insulator, with ...
