Nanosimulation of electron confinement in cerium doped zinc oxide nanowire structure for light emitting devices

Nanosimulation of Cerium (Ce) doped Zinc Oxide (ZnO) nanowire has been carried out for nanowires structure of Ce doped ZnO/MgxZn1−xO using MATLAB. Electron confinement in Ce doped ZnO nanowire has been achieved by deducing wave function intensity from the solutions of Schrodinger equation. Eigen ene...

Description
Summary:Nanosimulation of Cerium (Ce) doped Zinc Oxide (ZnO) nanowire has been carried out for nanowires structure of Ce doped ZnO/MgxZn1−xO using MATLAB. Electron confinement in Ce doped ZnO nanowire has been achieved by deducing wave function intensity from the solutions of Schrodinger equation. Eigen energy has been computed using the Transfer Matrix Method (TMM). It is revealed from our analysis that increasing mole fraction of magnesium (Mg) increases Eigen energy. For 10% magnesium, Eigen energy was found to be 0.07eV and for 30% magnesium, it has got increased up to 0.09eV. Effect of Mg mole composition in barrier region on confinement of electron wave function spread has been investigated. Better confinement was obtained for increasing values of Mg mole composition.
