• Compositional and structural properties of pulsed laser-deposited ZnS:Cr films 

      Nematollahi, Mohammadreza; Yang, Xiaodong; Seim, Eivind; Vullum, Per Erik; Holmestad, Randi; Gibson, Ursula; Reenaas, Turid Worren (Journal article; Peer reviewed, 2016)
      We present the properties of Cr-doped zinc sulfide (ZnS:Cr) films deposited on Si(100) by pulsed laser deposition. The films are studied for solar cell applications, and to obtain a high absorption, a high Cr content ...
    • Molecular beam and pulsed laser deposition of ZnS:Cr for intermediate band solar cells 

      Nematollahi, Mohammadreza; Yang, Xiaodong; Aas, Lars Martin Sandvik; Ghadyani, Zahra; Kildemo, Morten; Gibson, Ursula; Reenaas, Turid Worren (Journal article, 2015)
      We have investigated the structural and optical properties of Cr-doped ZnS (ZnS:Cr) thin films (0–7.5 at.% Cr) for use in intermediate band solar cells. The films were grown on Si(100) in molecular beam epitaxy (MBE) and ...
    • Pulsed laser ablation and deposition of ZnS:Cr 

      Nematollahi, Mohammadreza; Yang, Xiaodong; Gibson, Ursula; Reenaas, Turid Worren (Journal article; Peer reviewed, 2015)
      We present a method to deposit films with a range of doping concentrations/dilute alloys, from a single target in pulsed laser deposition (PLD). Cr-doped ZnS films were deposited by ablating a target consisting Cr particles ...
