| dc.description.abstract | Optical, electrical, and electronic properties of materials are essential in the
fabrication of electronic devices. These properties can be improved through
doping and reduction of the size of a material to nanoscale. In this study,
copper doped magnesium-nickel (CuxMg1-xNiFe2O4, for x=0.00, 0.15, 0.30,
0.45, 0.60, 0.75, 1.00) ferrite nanoparticles were synthesized using the citragel auto combustion method. The electronic and optical properties were
evaluated using the scanning Kelvin probe microscopy (SKPM) and UVvisible, respectively. The UV-visible studies revealed that, the band gap
energy was at the range of 3.600-3.750 eV. The band gap was noted to
increase with copper content up to x=0.45 which then started to decrease.
The undoped sample displayed the lowest band gap energy in comparison
with the doped. SKPM analysis exhibited the surface potential in the range
4.361-5.002 eV for the area scan and 4.251-5.006 eV for the line scans for the
samples. The sample with x=0.75 showed a positive work function for both
area and line scans, and all the others had a negative work function. The
doped ferrite exhibited the properties that could be applied in optical devices,
storage devices, and recording devices.
