Direct Comparison of Structural and Electrical Properties of Epitaxial (001)-, (116)-, and (103)-Oriented SrBi2Ta2O9 Thin Films on SrTiO3 and Silicon Substrates
Anisotropies of the properties of the bismuth-layered perovskite SrBi2Ta2O9 (SBT) have been investigated using epitaxial thin films grown by pulsed laser deposition both on conducting Nb-doped SrTiO3 (STO) single crystal substrates and on Si(100) substrates. It has been found that the three-dimensional epitaxy relationship SBT(001)||STO(001); SBT ] 0 1 1 [ ||STO[100] can be applied to all SBT t...
متن کاملMonte Carlo simulations of epitaxial growth: comparison of pulsed laser deposition and molecular beam epitaxy
The influence of epitaxial growth method on surface morphology was explored using a solid-on-solid, rate equation, Ž . Ž . Monte Carlo simulation whose parameters were chosen to approximate 1=1 Si 001 . In simulations corresponding to molecular beam epitaxy, films of 10 monolayer thickness were deposited with a steady-state flux of 0.25 monolayersrs and an adatom energy of 0.3 eV. In simulation...
متن کاملFerromagnetism in pseudocubic BaFeO3 epitaxial films
Growth and properties of epitaxial BaFeO3 thin films in the metastable cubic perovskite phase are examined. BaFeO3 films were grown on 012 LaAlO3 and 001 SrTiO3 single crystal substrates by pulsed-laser deposition. X-ray diffraction shows that films grown between 650 and 850 °C yield an oxygen-deficient BaFeO2.5+x pseudocubic perovskite phase that decreases in lattice spacing with increasing gr...
متن کاملStructural characteristics of AlN films deposited by pulsed laser deposition and reactive magnetron sputtering: A comparative study
Aluminum nitride films have been deposited on Si~111! substrates at different substrate temperatures using two techniques; pulsed laser deposition or reactive magnetron sputtering. The films deposited by either of the techniques have been characterized by x-ray diffraction and transmission electron microscopy to determine the crystalline quality, grain size, and epitaxial growth relation with r...
متن کاملDependence of Magnetic Properties on Laser Ablation Conditions for Epitaxial La_{0.6}Sr_{0.4}MnO_{3} Thin Films Grown by Pulsed Laser Deposition
Epitaxial La0:6Sr0:4MnO3 (LSMO) thin films were grown by pulsed laser deposition. Relationships between magnetic properties of LSMO epitaxial thin films and ablation conditions such as ablated spot area and total incident laser energy in a pulsed laser deposition technique were studied. Ablated spot area was controlled by changing the focus lens position and total laser energy. Epitaxial growth...
