    • Electronic Properties of Functionalized Diamanes for Field-Emission Displays 

      Tantardini, Christian; Kvashnin, Alexander G.; Azizi, Maryam; Gonze, Xavier; Gatti, Carlo; Altalhi, Tariq; Yakobson, Boris I. (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-03-16)
      Ultrathin diamond films, or diamanes, are promising quasi-2D materials that are characterized by high stiffness, extreme wear resistance, high thermal conductivity, and chemical stability. Surface functionalization of multilayer graphene with different stackings of layers could be an interesting opportunity to induce proper electronic properties into diamanes. Combination of these electronic ...

    • Electronic Properties of Zn<inf>2</inf>V<inf>(1-x)</inf>Nb<inf>x</inf>N<inf>3</inf> Alloys to Model Novel Materials for Light-Emitting Diodes 

      Stratulat, Ana-Maria; Tantardini, Christian; Azizi, Maryam; Altalhi, Tariq; Levchenko, Sergey V.; Yakobson, Boris I. (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-10-04)
      We propose the Zn<sub>2</sub>V(<sub>1–x</sub>)Nb<sub>x</sub>N<sub>3</sub> alloy as a new promising material for optoelectronic applications, in particular for light-emitting diodes (LEDs). We perform accurate electronic-structure calculations of the alloy for several concentrations x using density-functional theory with meta-GGA exchange–correlation functional TB09. The band gap is found to vary ...
