摘要
Predominantly c[0001]-axis oriented aluminium-doped or undoped ZnO thin films were deposited using the helicon-wave excited plasma (HWP) as a sputtering source. The ZnO:Al thin films grown on soda-lime glass substrates exhibited narrow (0002) x-ray diffraction (XRD) peak with full width at half maximum (FWHM) of 0.29 deg. The ZnO:Al thin film deposited at 300 degrees C showed low resistivity of 5 x 10-4 Omega . cm without any additional annealings. Moreover, high optical transmittance greater than 85% was achieved in the visible spectral wavelengths. The HWP-sputtering method is expected as one of the versatile techniques for the preparation of semiconductor thin films.
