    • Changes of Fermi Surface Topology due to the Rhombohedral Distortion in SnTe 

      O'Neill, Christopher; Huxley, Andrew; Hermann, Andreas; Keen, Harry; King, Phil; Clark, Oliver
      Stoichiometric SnTe is theoretically a small gap semiconductor that undergoes a ferroelectric distortion on cooling. In reality however, crystals are always nonstoichiometric and metallic; the ferroelectric transition is ...
