By the method of multi-step growth, higher capacitance and thus a higher dielectric constant of 10.8 can be obtained. For the absence of the SiO2-x interfacial layer, the leakage current density is also higher.
Single crystal film is evidenced by synchrotron radiation XRD.
SiO2-x interfacial layer is formed during Tm2O3 deposition and removed by annealing.
