| Abstract | ||
| This work report on the calculations of the temperature dependence of young's modulus, dielectric, piezoelectric and elastic coefficients, poisson ratio and moment of inertia. These parameters are key parameters in the calculation of electrical energy generated from bending of ZnO nanowires (NW's) of length and width equals to 600nm and 50nm respectively due to applying an external force in one direction by an AFM tip (Atomic force microscopy) in the limits of elasticity. Results show that the young's modulus and dielectric coefficient show indirect proportionality with temperature while other parameters shows direct proportionality. These parameters having profound effect on the amount of the maximum generated voltage. The effect of the dependence of young modulus on temperature on the harvested electrical energy from ZnO nanowire formed on a substrate is minor. | ||
