| Description | Journal: Materials Research Express The objective of the present work is to study the effect of yttrium doping concentration on the microstructure and optical behavior of ZnO thin films, deposited by pulsed laser deposition on silicon (001) substrates. The microstructural analysis of doped ZnO thin films shows columnar growth of the ZnO (002) plane under tensile stress, confirmed by Raman shifts of the $E_{2}$ (high) mode. The optical properties are investigated by using a spectroscopic ellipsometer. Undoped and yttrium-doped ZnO films show high transparency in the visible region, and the estimated optical band gap energy is randomly shifted in the range 2.93–3.1 eV by increasing the yttrium doping level. Yttrium doping in ZnO is limited, which means that at doping concentrations higher than 3 wt.% of yttrium, the structural and optical properties show a shift towards those of undoped ZnO. |
