We have investigated the low-frequency noise and the sheet resistance of Al-doped ZnO thin films deposited by DC sputtering technique on glass substrate at different temperature. We characterized the noise below 100 kHz and obtained 1/f spectra. The 1/f noise normalized for bias, frequency and unit area, Cus is proportional with the sheet resistance Rsh• Sheet resistance decreases with the increasing...
ZnO films were deposited by de sputtering technique on glass and Pt/Si substrates. The effect of growth parameters is investigated on sheet resistance and noise. The 1/f noise normalized for bias, frequency and unit area, Cus is proportional with the sheet resistance Rsh• We found that the noise results correlate strongly with the crystalline structure of ZnO. For comparison, we have also studied...
We have investigated the low-frequency noise of ZnO film deposited by dc sputtering technique on glass substrate. We characterized the noise below 100kHz and obtained classical 1/ƒ spectra. We attempted to verify the validity of Hooge's empirical relation and to test its usefulness as a diagnostic tool. The 1/ƒ noise normalized for bias, frequency and unit area, Cus is proportional with the sheet...
