  • Energetically preferred Li+ ion jump processes in crystalline solids: Site-specific hopping in β-Li3VF6 as revealed by high-resolution 6Li 2D EXSY NMR 
    Bottke, Patrick; Hogrefe, Katharina; Kohl, Julia; Nakhal, Suliman; Wilkening, Alexandra; Heitjans, Paul; Lerch, Martin; Wilkening, H. Martin R． (New York, NY [u.a.] : Elsevier, 2023)
    The visualization of atomic or ionic jump processes on the Ångström length scale is important to identify the preferred diffusion pathways in solid electrolytes for energy storage devices. Two-dimensional high-resolution ...
  • Low-temperature DC conductivity of LiNbO 3 single crystals 
    Ruprecht, Benjamin; Rahn, Johanna; Schmidt, Harald; Heitjans, Paul (Berlin : Walter de Gruyter, 2012)
    We report on conductivity measurements of LiNbO3 single crystals with congruent composition in ambient atmosphere between 449 and 727 K which include the lowest temperatures covered so far. The ionic DC conductivity observed ...
  • Self-diffusion of lithium in amorphous lithium niobate layers 
    Rahn, Johanna; Hüger, Erwin; Dörrer, Lars; Ruprecht, Benjamin; Heitjans, Paul; Schmidt, Harald (Berlin : Walter de Gruyter, 2012)
    We investigated lithium self-diffusion in amorphous lithium niobate layers between 298 and 423 K. For the experiments, amorphous 6LiNbO 3/ 7LiNbO 3 isotope hetero-structures were deposited by ion beam sputtering and analysed ...
