• Proximity-Induced Superconductivity in CdTe-HgTe Core-Shell Nanowires 

      Hajer, Jan; Kessel, Maximilian; Brüne, Christoph; Stehno, Martin P; Buhmann, Hartmut; Molenkamp, Laurens W (Journal article; Peer reviewed, 2019)
      In this Letter we report on proximity superconductivity induced in CdTe–HgTe core–shell nanowires, a quasi-one-dimensional heterostructure of the topological insulator HgTe. We demonstrate a Josephson supercurrent in our ...
    • Residual strain in free-standing CdTe nanowires overgrown with HgTe 

      Kessel, Maximilian; Lunczer, Lukas; Tarakina, Nadezda V; Brüne, Christoph; Buhmann, Hartmut; Molenkamp, Laurens W (Journal article; Peer reviewed, 2019)
      We investigate the crystal properties of CdTe nanowires overgrown with HgTe. Scanning electron microscopy and scanning transmission electron microscopy confirm that the growth results in a high ensemble uniformity and that ...
