    Disordered systems are ubiquitous in nature and their study is complicated and often leads to controversial results. In any case, the important role of such systems in science and technological applications should not be ...
  • Electronic & ionic conduction & correlated dielectric relaxations in molecular solids 

    Zachariah, Manesh (Universitat Politècnica de Catalunya, 2016-11-17)
    Tesi
    Accés obert
    The study of crystalline materials has played a prominent role in solid state physics, whose basic theories were formulated for crystalline matter. However, disordered materials are more abundant in nature than crystalline ...
  • Guest-molecule dynamics and conductivity effects in carbon-based molecular solids 

    Mitsari, Efstratia (Universitat Politècnica de Catalunya, 2016-07-28)
    Tesi
    Accés obert
    Disordered systems are abundant in everyday life and so their study is of importance from a scientific and a technological point of view. The most common non-crystalline solid phases are structural glasses (e.g. window ...
  • Short-range order in disordered phases using neutron diffraction
