| Research Abstract |
Multi-phase structures were focused and the layer was grown by molecular beam epitaxy. Theoretical approach was also performed.
The structure was grown on the GaAs substrate which was a conventional material for the various device structures. ZnCdS was initially focused for the candidate of the multi-phase structure since both ZnS and CdS exhibit Zincblende structures as well as Wurtzite structures. The other advantage of this material is that the lattice matching between GaAs and ZnCdS is possible.
Other materials system lattice match to the InP substrate was also considered from the theoretical calculation.
1. The crystal structure of ZnCdS epilayers grown by MBE or by MOCVD can be tuned, and zincblende structures as well as wurtzite structures can be formed by changing the growth parameters.
2. The crystal structre can be controlled regardless of the substrate surface arrangement, namely (001), (111)A, and (111)B surfaces.
3. 4.5. X-ray phi-scan was proposed and shown that it was a simple and powerful technique to distinguish the two structures.
6.7. ZnCdMgOSSe was also considered as a multi-pahse structure materials which can be lattice match to InP.
