Author:Ouma, CNM; Meyer, WEDate:Jun 2016Using both the Perdew-Burke-Ernzerhof (PBE) functional and the hybrid functional of Heyd-Scuseria-Ernzerhof (HSE06), the metastability of the carbon-substitutional-carbon-interstitial (C(subs)C(subi)) defect in silicon has been investigated ...Read more
Author:Valdes, M; Modibedi, Remegia M; Mathe, Mahlanyane K; Hillie, T; Vazquez, MDate:May 2014Cu(sub2)ZnSnS(sub4)(CZTS) thin films have been prepared using Electrochemical Atomic Layer Deposition (EC-ALD)and also by one-step conventional constant potential electrodeposition. Optimal deposition conditionswere investigated using cyclic ...Read more
Author:Linganiso, EC; Rodrigues, R; Mhlanga, SD; Mwakikunga, Bonex W; Coville, NJ; Hümmelgen, IADate:Dec 2013The wide band-gap semiconductor material gallium nitride was synthesized using a one step microwave-assisted solution phase technique. The synthesized GaN nanocrystals showed an intense ultraviolet-blue emission typical of GaN materials. ...Read more
Author:Saasa, Valentine R; Malwela, Thomas; Lemmer, Yolandy; Beukes, M; Mwakikunga, Bonex WDate:Oct 2020Hierarchical nanostructured Co-doped WO3 with carbon as template has been successfully synthesised through facile sol-gel method. The synthesised Co-doped WO3 was characterized by X-ray diffraction, Scanning electron microscopy, Transmission ...Read more
Author:Wilson, KC; Manikandan, E; Basheer Ahamed, M; Mwakikunga, Bonex WDate:2014We report on surface morphology changes of in situ tin (Sn) doped cadmium sulphide (CdS) thin film nanostructures prepared on a glass substrate using the chemical bath deposition (CBD) technique. Sn-doping in the presence of triethanolammine ...Read more
