Macroscopic polarization in the nominally ergodic relaxor state of lead magnesium niobate

Dragan Damjanovic, Lukas Riemer, Yang Li, Kanghyun Chu, Brahim Dkhil

Macroscopic polarity and its dynamic response to external electric fields and temperature in the nominally ergodic relaxor phase of pristine lead magnesium niobate crystals and ceramics, Pb(Mg1/3Nb2/3)O3 (PMN), were investigated. Dynamic pyroelectric measu ...

Towards Oxide Electronics: a Roadmap

Ulf Anders Hagfeldt, Francisco Sanchez, Mauro Fanciulli, Monica Marcela Lira Cantu, Brahim Dkhil

At the end of a rush lasting over half a century, in which CMOS technology has been experiencing a constant and breathtaking increase of device speed and density, Moore's law is approaching the insurmountable barrier given by the ultimate atomic nature of ...

Single-domain (110) PbTiO3 thin films: Thermodynamic theory and experiments

Nava Setter, Alexander Tagantsev, Mahamudu Mtebwa, Brahim Dkhil

We report the thermodynamic potential for single-domain (110) thin films epitaxially grown on dissimilar cubic substrates. Using different sets of paraelectric phase elastic compliance coefficients of PbTiO3 single crystal, calculated from the experimental ...

Negative-pressure-induced enhancement in a freestanding ferroelectric

Nava Setter, Alexander Tagantsev, Marco Cantoni, Tomas Sluka, Alexander Kvasov, Silviu Cosmin Sandu, Jin Wang, Xiankui Wei, Brahim Dkhil

Ferroelectrics are widespread in technology(1), being used in electronics and communications(2), medical diagnostics and industrial automation. However, extension of their operational temperature range and useful properties is desired(3-5). Recent developm ...

Low-Symmetry Phases in Ferroelectric Nanowires

Nava Setter, Brahim Dkhil

Ferroelectric nanostructures have recently attracted much attention due to the quest of miniaturizing devices and discovering novel phenomena. In particular, studies conducted on two-dimensional and zero-dimensional ferroelectrics have revealed original pr ...
