    • Centrosymmetric Tetragonal Tungsten Bronzes A4Bi2Nb10O30 (A = 2 Na, K, Rb) with a Bi 6s Lone Pair 

      Nylund, Inger-Emma; Zeiger, Caren Regine; Peng, Ding; Vullum, Per Erik; Walker, Julian; Einarsrud, Mari-Ann; Grande, Tor (Peer reviewed; Journal article, 2022)
      A first-principles study of the tetragonal tungsten bronze (TTB) K4Bi2Nb10O30 has suggested that the Bi 6s lone pair causes in-plane polarization (within the a–b plane), corresponding to the one found in Pb5Nb10O30 (PN), ...

    • On the Solubility of Bi in Tetragonal Tungsten Bronzes 

      Zeiger, Caren Regine; Williamson, Benjamin Albert Dobson; Walker, Julian Bradley; Einarsrud, Mari-Ann; Grande, Tor (Peer reviewed; Journal article, 2024)
      Ferroelectric Pb5Nb10O30 (PN) tetragonal tungsten bronze (TTB) forms solid solutions that exhibit morphotropic phase boundaries (MPBs). Successful replacement of PN with TTBs containing Bi could advance lead-free TTB MPBs. ...
