Instrument-independent specification of the diffraction geometry and polarization state of the incident X-ray beam

This work augments the proposal of Schwarzenbach & Flack [J. Appl. Cryst. (1989), 22, 601-605], who have advocated the use of a diffractometer-independent definition of the azimuthal angle

\psi

to specify the diffractiongeometry of a Bragg reflection. It ...

Polarization sensitive diffuser

Hans Peter Herzig, Toralf Scharf

With help of liquid crystal polymers (LCP) a polarization sensitive diffuser has been realized. By using convex microstructures made of LCP and an index matching layer, two distinct functions depending on the orientation of the device and the polarization ...

Nature of nonlinear imprint in ferroelectric films and long-term prediction of polarization loss in ferroelectric memories

Nava Setter, Alexander Tagantsev, Igor Stolichnov

The phenomenon of polarization imprint consisting of the development of a preferential polarization state in ferroelectric films is known as one of the major issues impacting the development of high density ferroelectric memories. According to the commonly ...

Three-dimensional ferroelectric domain imaging of bulk Pb(Zr,Ti)O-3 by atomic force microscopy

Nava Setter, Enrico Colla

We report on the ferroelectric domain evolution as a function of the depth of the surface of 100 mum thick bulk Pb(Zr,Ti)O-3 (PZT) doped with 2% Nb. Ferroelectric domain imaging (FDI) was performed by piezoelectric detection assisted by atomic force micros ...

Patterned and self-assembled ferroelectric nano-structures obtained by epitaxial growth and e-beam lithography

Simon Bühlmann

The continuous downscaling of microelectronic circuits combined with increasing interest in ferroelectric thin films for non-volatile random access memories (FeRAM) is drawing great attention to small ferroelectric thin film structures. There are various c ...

Mechanical stress effect on imprint behavior of integrated ferroelectric capacitors

Alexander Tagantsev

Stress-induced changes in the imprint and switching behavior of (111)-oriented Pb(Zr,Ti)O-3 (PZT)-based capacitors have been studied using piezoresponse force microscopy. Visualization of polarization distribution and d(33)-loop measurements in individual ...

Dimensionally Stable Anode-Type Anode Based on Conductive p-Silicon Substrate

Christos Comninellis, György Foti, Lassine Ouattara, Ilaria Duo, Marco Panizza

In the search for a good dimensionally stable anode-type electrode, p-silicon (1-3 mW cm) has been chosen as the substrate material due to its high anodic stability and its reasonable cost compared to titanium and tantalum. Several p-Si/IrO2 electrodes hav ...

Evidence for forward domain growth being rate-limiting step in polarization switching in < 111 >-oriented-Pb(Zr0.45Ti0.55)O-3 thin-film capacitors

Nava Setter

We studied polarization switching of 295 nm thick -oriented-Pb(Zr0.45Ti0.55)O-3 (PZT) thin-film capacitors through a polarization hysteresis loop and piezoelectric force microscopy (PFM) on top of the Pt electrode. Positive voltage pulses of 450 kV/cm ...

Unusual size effect on the polarization patterns in micron-size Pb(Zr,Ti)O-3 film capacitors

Nava Setter, Alexander Tagantsev, Igor Stolichnov, Enrico Colla

Direct observation of polarization distribution at nanoscale by scanning force microscopy across partially etched Pb(Zr,Ti)O-3 film ferroelectric capacitors with size 2x3 mum and preferential orientation (111) has revealed an anomalous polarization pattern ...

Size and top electrode-edge effects on fatigue in Pb(Zr,Ti)O-3 capacitors with Pt-electrodes

Nava Setter, Alexander Tagantsev, Enrico Colla

The occurrence of switching-induced suppression of the remanent polarization (fatigue) in Pb(Zr,Ti)O-3 (PZT) ferroelectric capacitors with comb shaped top electrodes was studied by means of scanning force microscopy assisted by a lock-in amplifier. Fatigue ...
