“…Thus, yttrium doping will theoretically enhance electrical and optical properties of ZnO. Because, in the earlier studies, it has been found that Y doping enhanced UV emission (optical properties) [1,12,[18][19][20][21][22], electrical conductivity [18,19,23], gas sensor characteristics [14,20] and ferromagnetism property of ZnO [15], the more studies about investigation of Y doping effect on the features of zinc oxide structure should be made in order to fabricate more effective ZnO semiconductor materials.…”
