effect of magnetic field on the preparation of cu doped zinc oxide nanostructures in different temperatures

We tried to overcome some industrial defects of crystals (cu doped zno) while improving some of its features through the use of three important factors: doping (5% cu), temperature, and magnetic field effect. we have identified some of its properties and dimensions through uv, xrd and fe-sem measurements. we have succeeded in preparing cu doped zno nanostructure with different lengths and diameters, more uniform crystals, as well as multiple energy gap values. this allows it to be used in a wide range of technology applications. energy gap values are clearly affected by the increase in temperature and the presence of the magnetic field. the size of the crystals increases with the increase in temperature and the presence of the magnetic field. the crystals become more uniform and the artificial defects decrease. the change in the dimensions of the crystals with increasing temperature depends on the nature of doping and the nature of semiconductor metallurgy. lengths and diameters of the nanostructure increase with increasing temperature and with the presence of the magnetic field, which means more attractive and useful features. enhanced catalytic efficiency of cu-doped zno is attributed to intrinsic oxygen vacancies mainly due to high surface to volume ratio in nanorods and as well as extrinsic defect due to cu doping. while the method (cu doped zno) demonstrates the half-metallic ground state as well and the high ferromagnetic stability for all the measured cu concentrations mostly within the generalized gradient approximation.
