MgxZn1−xO is crucial for applications as a barrier layer or quantum wells in ZnO/MgxZn1−xO heterostructures.
Energy bandgap of MgxZn1−xO : 3.37~ 7.8 eV (by incorporating Mg into ZnO)
However, the crystal structure of MgO is different from that of ZnO
- MgO : rock-salt cubic structure. ZnO : wurtzite hexagonal structure.
The different crystal structure induces the l
3.Result and Discussion
Fig. 1 shows the XRD patterns from the as-grown films. There is no new peak appearing when RF power of Ge is 0 W except for three peaks of ZnO (1 0 0), (0 0 2)and (0 0 4) located at 2θ = 30.888, 34.218, and 72.138, respectively. At RF power 100 W, these three peaks shift toward larger angle apparently and their intensity has also enhanced slightly. This indicates tha
