Effect of annealing atmosphere on characteristics of kaolin-doped zinc oxide disks

This study elucidates the effect of the annealing environment (oxygen and nitrogen) on the properties of kaolin-doped ZnO disks. The findings showed that, in comparison to the sample annealed in O2 ambient, the sample annealed in N2 has a greater average grain size. The tensile stress, lattice const...
