| Abstract | ||
| The Hall effect tests showed that the thin films of(LixNi2-xO2) have a carriers charge (p-type) at all doping ratios. The concentration of carriers increases from (0.257* 1017- 48.07*1017) cm3 , as well as increasing electrical conductivity by increasing the doping from (2.82 * 10-3- 128.65 * 10-3) eV, while the Hall coefficient decreases from (2.423 * 103-0.013 *103) cm3/C , The continuous conductivity measurements showed a decrease in activation energy by increasing doping (Ea1 = 0.13 , Ea2 = 0.278) eV, at x=0.0 and becomes(Ea1=0.074eV,Ea2=0.117eV)at x=0.55, The alternating conductivity tests showed that, Alternate conductivity as well as capacitance and both real and imaginary dielectric constant increases with increasing doping ratio. | ||
