Characterization of Cu2O Thin Film Grown by Molecular Beam Epitaxy

Article Preview

Abstract:

We report the growth of Cu2O thin films on glass and MgO(100) substrates by molecular beam epitaxy. Crystal orientation of Cu2O thin films on glass substrate were changed from (100) to (111) with increasing the deposition rate. The Cu2O thin films were epitaxially grown on MgO(100) substrate with an orientation relationship of Cu2O(110) // MgO(100). The film quality and electrical properties of Cu2O thin films were changed with deposition rate. The slow deposition rate resulted in high conductivity and mobility, as well as good crystallinity and orientation.
