The ferroelectric-paraelectric phase transition in BiFeO3: crystal structure of the orthorhombic beta-phase
Donna C. Arnold, Kevin S. Knight, Finlay D. Morrison +1
A detailed investigation using variable temperature powder neutron diffraction demonstrates that BiFeO3 undergoes a phase transition from the ferroelectric alpha phase (rhombohedra…
Conformal oxide coating of Carbon Nanotubes
S. Kawasaki, G. Catalan, H. Fan +8
The International Roadmap for Ferroelectric Memories requires three-dimensional integration of high-dielectric materials onto metal interconnects or bottom electrodes by 2010. We r…
High-Field Conduction in Barium Titanate
J. F. Scott, F. D. Morrison, P. Zubko +5
We present current-voltage studies of very thin (ca. 77 nm) barium titanate single crystals up to 1.3 GV/m applied field. These show that the mechanism of leakage current at high f…
Intrinsic Dielectric Response in Ferroelectric Nanocrystals
M. M. Saad, P. Baxter, R. M. Bowman +3
Measurements on 'free-standing' single crystal barium titanate capacitors with thicknesses down to 75nm show a dielectric response typical of large single crystals rather than conv…
Ferroelectric Nanotubes
F. D. Morrison, Y. Luo, I. Szafraniak +12
We report the independent invention of ferroelectric nanotubes from groups in several countries. Devices have been made with three different materials: lead zirconate-titanate PbZr…
