Thickness effect on the ferroelectric properties of La-doped HfO<sub>2</sub> epitaxial films down to 4.5 nm
نویسندگان
چکیده
Epitaxial La:HfO 2 films of less than 7 nm have a high remanent polarization about 30 ?C cm ?2 , and show slight wake-up, endurance at least 10 cycles retention more years, with both latter properties measured the same poling voltage.

Dependence of Epitaxial Thin Films Properties on Template Thickness
In our previous report, we demonstrated the growth of high-quality epitaxial Co-doped (Ba-122) thin films using single crystalline (STO) templates on (LSAT) substrates with pulsed laser deposition (PLD). Here, we report the dependence of the structural and superconducting properties of Ba-122 thin films on STO templates that were 2-150 unit cell (u.c.) thick. We obtained genuine epitaxial thin ...
متن کاملGrowth and physical properties of highly oriented La-doped (K,Na)NbO3 ferroelectric thin films
Lead-free (K,Na)NbO3 (KNN) and La doped (K,Na)NbO3 (KNN-La) thin films were grown on SrTiO3 substrates by chemical solution deposition method. The effect of adding different amounts of Na and K excess (0-20 mol%) has been investigated. The results confirm the necessity to add 20 mol% excess amounts of Na and K precursor solutions in order to avoid the formation of the secondary phase, K4Nb6O17,...

متن کاملEffect of Thickness on the Electrical and Optical Properties of Sb Doped SnO2 (ATO) Thin Films
This work reports the preparation and characterization of (SnO2) thin films doped with 7 mol% Sb2O3. The films were prepared by the polymeric precursor method, and deposited by spin-coating, all of them were deposited on amorphous silica substrate. Then, we have studied the thickness effect on the microstrutural, optical and electric properties of these samples. The microstructural characteriza...
متن کاملGiant flexoelectric effect in ferroelectric epitaxial thin films.
We report on nanoscale strain gradients in ferroelectric HoMnO(3) epitaxial thin films, resulting in a giant flexoelectric effect. Using grazing-incidence in-plane x-ray diffraction, we measured strain gradients in the films, which were 6 or 7 orders of magnitude larger than typical values reported for bulk oxides. The combination of transmission electron microscopy, electrical measurements, an...
