| Abstract: | An electrochemical approach was used to synthesise nickel iron sulphide (NiFeS) materials in this work. The prepared NiFeS underwent a thorough investigation, which included analyses of its optical, electrical, structural, morphological, elemental, and functional group properties. Cubic crystal formations with prominent peaks were visible from the structural pattern. Nanoflakes and pebbles were visible, and their elements were determined through elemental dispersive X-ray diffractometer (EDX) spectrum. The film's crystallinity increased after incorporating carbon ions and its optical properties improved, with energy band gap values ranging from 1.50 eV to 1.15 eV as the peaks became more distinct. The materials produced could be utilised in the production of solar cells and optoelectronic devices. The electrical conductivity diminishes with increasing thickness. Carbon ion radiation increases carrier concentration, which increases electrical conductivity. NiFeS was irradiated using 500 keV carbon C++ ions beam irradiation NiFeS without irradiation has a bandgap of 1.50 eV, while the irradiated material had bandgaps between 1.35-1.15 eV. The film's crystallinity was enhanced by incorporating carbon ions Nanogels and nanoflakes were seen in the micrographs of the unirradiated materials. [ABSTRACT FROM AUTHOR] |
