Effect of deposition temperature on the formation of defect phases in BiFeO3 thin films
We report the effects of deposition temperature on the evolution of defect and second phases and on the ferroelectric properties of BiFeO3 thin films. We grew BiFeO3 thin films on (001) SrTiO3 substrates by using...

Growth of High-Quality Pb(ZrxTi1-x)O3 Films by Peroxide MBE and Their Optical and Structural Characteristics
The growth of Pb(ZrxTi1-x)O3 (PZT) films by molecular beam epitaxy was demonstrated. Single-crystal, single-phase PZT films were grown on (001) SrTiO3 substrates at a growth temperature of 600°C. In situ monitori...

Structural and Optical Properties of PbTiO3 Grown on SrTiO3 Substrates by Peroxide MBE
Lead titanate (PbTiO3), a ferroelectric material with perovskite structure, has received a great deal of attention owing to a unique combination of its piezoelectric, pyroelectric, dielectric, electo- and acousto...

Optical Study of SiO2/nanocrystalline-Si Multilayers Using Ellipsometry
Using variable-angle spectroscopic ellipsometry, we measure the pseudo-dielectric functions of as-deposited and annealed SiO2/SiOx multilayers (MLs). The SiO2(2nm)/SiOx(2nm) MLs have been prepared under various d...
