“…For sample S2 of (Mg,Zn)O grown on MgO(110), no distinct diffraction peaks are visible other than those observed from the MgO(110) substrate, as shown in Figure 2A. In our previous study, 26 it was identified that the growth direction of ZnO thin film grown on MgO(110) substrate was along [10][11][12][13]. It is possible that the (Mg,Zn) O film grown on the MgO(110) substrate was also oriented along [10][11][12][13], in which case, the corresponding peak in the XRD result would be located at 62.86 , which could have overlapped with the peak of the MgO(110) substrate located at 62.30 .…”

(Mg,Zn)O films with various growth orientations were prepared on the MgO substrates with different surface structures using oxygen plasma‐assisted molecular beam epitaxy. X‐ray diffraction (XRD) revealed that the crystallographic orientation of (Mg,Zn)O thin films transforms from the polar c‐plane (0001) to a two‐fold‐symmetry inclined plane and then to the nonpolar m‐plane (10–10) as the substrate template changes from MgO(111) to MgO(011) and then to MgO(001). In addition, the surface topography and film roughness were monitored by atomic force microscopy. Interestingly, the electronic structures of the three films exhibited orientation‐dependent features, as revealed by synchrotron‐based X‐ray absorption spectroscopy. In addition, all of the (Mg,Zn)O thin films showed high optical transmittance (over 85%, 400–800 nm) and large energy gaps (around 3.33 eV). Our systematic study of the substrate‐influenced film characteristics demonstrates a method of tailoring thin films using the same substrate with different crystallographic orientations.

“…Specifically, the TEM images show the apparent interface of ZnO/MgO, grain boundaries and defects as well as indicate that the interface also has a tremendous influence on the electronic and optical properties [31,32]. From theoretical predictions of the optical properties of a supercell [20,30], the optical spectrum reflects some characteristic peaks in comparison with the experimental absorbance.…”

“…In addition, the strict computational cost requirements of constructing interface systems for the excitonic effect cannot be avoided, which must be taken into account to estimate the exact absorption onset for both ZnO and MgO [33]. Hence, in terms of experiments, the interface systems are closer to the real atomic structures [31,32], but an investigation of this relationship and structural factor are beyond the current purposes of controlling the concentration and external pressure in this study.…”

Influence of Stress on Electronic and Optical Properties of Rocksalt and Wurtzite MgO–ZnO Nanocomposites with Varying Concentrations of Magnesium and Zinc

The structural, electronic and optical properties of stressed MgO–ZnO nanocomposite alloys with concentrations of Zn and Mg varying from 0.125 to 0.875 were studied using ab initio simulations. Two crystal structures are considered for the initial MgO–ZnO alloys: the rocksalt Mg\({_\text{1-x}}\)Zn\({_\text{x}}\)O and wurtzite Zn\({_\text{1-x}}\)Mg\({_\text{x}}\)O phases. For rocksalt Mg\({_\text{1-x}}\)Zn\({_\text{x}}\)O, the optimized structures are stable at pressures below 10 GPa. The larger the Mg concentration and pressure, the wider the \({E_{g}}\) of the rocksalt phase. In contrast, the optimal geometries of wurtzite Zn\({_\text{1-x}}\)Mg\({_\text{x}}\)O reveal a diversity of possibilities, including rocksalt, wurtzite and mixed phases. These effects lead to the fact that the optical properties of wurtzite Zn\({_\text{1-x}}\)Mg\({_\text{x}}\)O not only demonstrate the properties of the wurtzite phase but also indicate the optical features of the rocksalt phase. In addition, mixed phases of Zn\({_\text{1-x}}\)Mg\({_\text{x}}\)O simultaneously provide the characteristics of both wurtzite and rocksalt phases with the same structures in different dielectric matrices.
