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

      Luneng, Jenny Louise (Master thesis, 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 ...

      Johannessen, Karen Cecilie (Master thesis, 2012-10-29)
      The origin of the mountainous topography in southern Norway is at present unresolved. Post-Devonian sediments are absent onshore, making quantification of crustal uplift and fault displacements difficult. Low-temperature ...
