Aluminum doped-zinc oxide (AZO) thin films were prepared on glass substrate by radio-frequency (RF) sputtering at room temperature. The sheet resistance, Rsh [Ω] the resistivity, ρ [Ω·cm] and the 1/f noise were studied as a function of thickness, t from 50nm to 450nm. The eddy current characterized the homogeneity of AZO thin films. The surface morphology has been analysed by atomic force microscopy...
We have investigated the effects of thickness on the electrical properties of Co2% and In1% co-doped ZnO films (CIZO) grown on glass substrates at room temperature by Radio Frequency (RF) magnetron sputtering technique. The sheet resistance Rsh [Ω], the resistivity ρ [Ω.cm], and the 1/f noise have been analysed as a function of thickness from 50 nm to 450 nm. The electrical properties and 1/f fluctuation...
AZO thin films were prepared on glass substrate by RF sputtering at room temperature. The sheet resistance, Rsh [Ω] the resistivity, ρ[Ω.cm] and the 1/f noise were studied as a function of thickness, t from 50 nm to 450 nm. The 1/f noise normalized for bias, frequency and unit area, Cus is proportional with the sheet resistance Rsh. Our results show that the resistivity decreases with thickness. The...
