Mgx Zn 1−x O thin lms were deposited on glass substrate with x varied between 0.01 and 0.05 by spray pyrolysis at a temperature of 450 °C. The structural investigation showed that all thin lms had ZnO wurtzite structure with a preferred (002) orientation. The gap energy was calculated using Tauc's plot and it decreased over the Mg content by 0.07 eV. The charge carriers' density dropped by an order of 10 5 as Mg content increased whereas the resistivity and the mobility increased. SEM observations revealed a signi cant difference between undoped and doped thin lms. A 632.8 nm laser source prism coupler revealed 2 optical modes for every thin lm in each Transverse Electric and Transverse Magnetic mode, the birefringence of the Mg doped lms was positive. Both ordinary and extraordinary refractive indexes were found to decrease as the Mg content increased. Great intention has been paid to the relation between the refractive, charge carriers density and the optical band gap.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
