    • Carbon single-electron point source controlled by Coulomb blockade 

      Kleshch, Victor I; Porshyn, Vitali; Orekhovc, Anton S; Orekhov, Andrey S; Lützenkirchen-Hecht, Dirk; Obraztsov, Alexander N (Elsevier BV, 2020)
      The Coulomb blockade effect is commonly used in solid state electronics for the control of electron flow at the single-particle level. Potentially, it allows the creation of single-electron point sources demanded for ...

    • Conduction mechanisms and voltage drop during field electron emission from diamond needles 

      Torresin, Olivier; Borz, Mario; Mauchain, Julien; Blum, Ivan; Kleshch, Victor I; Obraztsov, Alexander N; Vella, Angela; Chalopin, Benoit (Elsevier BV, 2019)
      We report results of experimental investigation of field electron emission from diamond nanoemitters. The measurements were performed with single crystal diamond needles fixed at tungsten tips. The voltage drop along diamond ...
