A feasible and low-cost green route to prepare ZnO with n or p-type conductivity by changing the parsley extract concentration

C. K. Zagal-Padilla et al.

Summary: ZnO samples were prepared with parsley extract as natural reducing agents at three different concentrations in this study. The incorporation of Mg in ZnO led to changes in lattice parameter and bandgap, affecting the conductivity type and photo-response of the synthesized samples. The interaction of Mg with the crystalline structure resulted in the formation of predominant native defects in ZnO.

DFT study of electronic properties of N-doped ZnO and ZnO/Cu(111) bilayer films

Ho Viet Thang et al.

Summary: The electronic properties of N-doped ZnO/Cu(111) bilayer films were studied using the DFT+U method, showing differences in oxidation state of N compared to free-standing ZnO bilayer films. The extra negative charge of N in N:ZnO/Cu(111) was attributed to electron transfer from the Cu support. This difference in oxidation state of the N dopant was demonstrated through analysis of Bader charge, magnetization, and density of states.
