    • Electron-magnon coupling and quasiparticle lifetimes on the surface of a topological insulator 

      Mæland, Kristian; Røst, Håkon Ivarssønn; Wells, Justin William; Sudbø, Asle (Peer reviewed; Journal article, 2021)
      The fermionic self-energy on the surface of a topological insulator proximity coupled to ferro- and antiferromagnetic insulators is studied. An enhanced electron-magnon coupling is achieved by allowing the electrons on the ...

    • Electronic and structural properties of the natural dyes curcumin, bixin and indigo 

      Michels, Leander; Richter, Annika; Chellappan, Rajesh Kumar; Røst, Håkon Ivarssønn; Behsen, Alenka Djarmila; Wells, Kristin Høydalsvik; Leal, Luciano; Santana, Vilany; Blawid, Rosana; da Silva, Geraldo J.; Cooil, Simon; Wells, Justin William; Blawid, Stefan (Peer reviewed; Journal article, 2021)
      An optical, electronic and structural characterisation of three natural dyes potentially interesting for application in organic solar cells, curcumin (C21H20O6), bixin (C25H30O4) and indigo (C16H10N2O2), was performed. ...

    • A Simplified Method for Patterning Graphene on Dielectric Layers 

      Røst, Håkon Ivarssønn; Reed, Benjamen P.; Strand, Frode Sneve; Durk, Joseph A.; Evans, D. Andrew; Grubišić-Čabo, Antonija; Wan, Gary; Cattelan, Mattia; Prieto, Mauricio J.; Gottlob, Daniel M.; Tǎnase, Liviu C.; De Souza Caldas, Lucas; Schmidt, Thomas; Tadich, Anton; Cowie, Bruce C. C.; Chellappan, Rajesh Kumar; Wells, Justin William; Cooil, Simon P. (Peer reviewed; Journal article, 2021)
      The large-scale formation of patterned, quasi-freestanding graphene structures supported on a dielectric has so far been limited by the need to transfer the graphene onto a suitable substrate and contamination from the ...
