Synthesis and characteristics of Mg doped ZnO thin films: Experimental and ab-initio study

Influence of the aqueous solution composition on the morphology of Zn1−xMgxO films deposited by spray pyrolysis

“…[11][12][13] ZnO can be doped with group-13 elements to enhance the intrinsic n-type conductivity or with divalent elements such as Mg or Cd, which increase or decrease the band gap due to differences in the electron affinity. 14,15 The tunability of the band gap with Mg incorporation renders Zn 1Àx Mg x O especially interesting for semiconductor devices, as the energy band alignment at the heterojunction is of utmost importance. An example is given by Hariskos et al who reported the application of Zn 1Àx Mg x O as n-type buffer layer in Cu(In,Ga)(Se,S) 2 -based thin film solar cells 16 or Minami et al who applied a Zn 1Àx Mg x O buffer layer in Cu 2 O-type solar cells.…”

“…Among them, the ultrasonic atomizing system has been proven to be precise, controllable and repeatable. 29 Zn 1Àx Mg x O films deposited by spray pyrolysis have been reported frequently, 15,[30][31][32][33][34][35][36][37][38][39][40][41] but in the majority of the reports toxic or flammable solvents, such as methanol [30][31][32] or ethanol, 15,34,35 are used. Studies on water-based solutions are rare.…”

Origin of Antibacterial Activity of ZnO Nanoparticles: The Roles of Protonic and Electronic Conductions

“…In addition, the conductivity of the porous sample is decreased by Mg or Ca doping. It is reported that the dopants form deep trap levels in the bandgap of ZnO, which results in a decrease in electronic conductivity . Therefore, a decrease in conductivity by Mg or Ca doping is attributed a decrease in electronic conductivity.…”

Effect of Mg Doping on Structural and Optical Properties of Al-Mg Co-doped ZnO Thin Films Deposited via Sol-gel Technique

“…Similar results have also been reported [37,38] . Another explication had cited by Rouchdi et al [39] . They have related this increasing of band gap in to the defects created after Mg 2+ substitution for Zn 2+ and then enters the ZnO lattice due to variation in their ionic radius.…”
