In detail, single crystal WSe₂ is codoped with 4 at% Co and various concentrations of Nb by employing the physical ion implantation method. Raman, X-ray diffraction and X-ray photoelectron spectroscopy results reveal the effective substitutional doping of implanted elements (Co and Nb). Magnetic measurements illustrate that both un-doped and 4 at% Co doped WSe₂ show weak ferromagnetism whereas magnetization is strongly enhanced when Co and Nb are codoped into WSe₂. The magnetization is comparable with a ferromagnet, which may be attributed to Co, Nb doping and defects. In addition, a large coercivity of ≈1.2 kOe is observed in the 1 at% Nb–4 at% Co codoped WSe₂ sample, which may be ascribed to the combined effect of doping-induced stress, defect-dictated pinning and anisotropy of Nb-Se bond owing to the charge transfer between Nb and Se ions.]]> Tue 05 Jul 2022 11:09:36 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:50948 Mon 13 May 2024 12:58:56 AEST ]]>
