Ferroelectricity and tetragonality in ultrathin PbTiO3 films.
The evolution of tetragonality with thickness has been probed in epitaxial c-axis oriented PbTiO3 films with thicknesses ranging from 500 down to 24 A. High resolution x ray pointed out a systematic decrease of the c-axis lattice parameter with decreasing film thickness below 200 A. Using a first-principles model Hamiltonian approach, the decrease in tetragonality is related to a reduction of t...
متن کاملFerroelectricity driven magnetism at domain walls in LaAlO3/PbTiO3 superlattices
Charge dipole moment and spin moment rarely coexist in single-phase bulk materials except in some multiferroics. Despite the progress in the past decade, for most multiferroics their magnetoelectric performance remains poor due to the intrinsic exclusion between charge dipole and spin moment. As an alternative approach, the oxide heterostructures may evade the intrinsic limits in bulk materials...

15 صفحه اولGaN Based Nanomaterials Fabrication with Anodic Aluminium Oxide by MOCVD
A highly self-ordered hexagonal array of cylindrical pores has been fabricated by anodizing a thin film of Al on substrate and subsequent growth of GaN and InGaN in these nanoholes has been performed. This AAO templatebased synthesis method provides a low cost process to fabricate GaN-based nanomaterials fabrication.
