12 p, 510.0 KB A flexoelectric microelectromechanical system on silicon / Bhaskar, Umesh K. (Institut Català de Nanociència i Nanotecnologia) ; Banerjee, Nirupam (University of Twente. Faculty of Science and Technology) ; Abdollahi, Amir (Institut Català de Nanociència i Nanotecnologia) ; Wang, Zhe (Cornell University. Department of Materials Science and Engineering) ; Schlom, Darrell G. (Cornell University. Department of Materials Science and Engineering) ; Rijnders, Guus (University of Twente. Faculty of Science and Technology) ; Catalan, Gustau (Institut Català de Nanociència i Nanotecnologia)
Flexoelectricity allows a dielectric material to polarize in response to a mechanical bending moment and, conversely, to bend in response to an electric field. Compared with piezoelectricity, flexoelectricity is a weak effect of little practical significance in bulk materials. [...]

Using scanning probe microscopy, we measure the out-of-plane mechanical response of ferroelectric 180° domain walls and observe that, despite separating domains that are mechanically identical, the walls appear mechanically distinct-softer-compared to the domains. [...]

35 p, 32.3 MB Strain-Engineered Ferroelastic Structures in PbTiO3 Films and Their Control by Electric Fields / Langenberg, Eric (Cornell University) ; Paik, Hanjong (Cornell University) ; Smith, Eva H. (Cornell University) ; Nair, Hari P. (Cornell University) ; Hanke, Isabelle (Leibniz-Institut für Kristallzüchtung) ; Ganschow, Steffen (Leibniz-Institut für Kristallzüchtung) ; Catalan, Gustau (Institut Català de Nanociència i Nanotecnologia) ; Domingo Marimon, Neus (Institut Català de Nanociència i Nanotecnologia) ; Schlom, Darrell G. (Kavli Institute at Cornell for Nanoscale Science)
We study the interplay between epitaxial strain, film thickness, and electric field in the creation, modification, and design of distinct ferroelastic structures in PbTiO thin films. Strain and thickness greatly affect the structures formed, providing a two-variable parameterization of the resulting self-assembly. [...]

Departmento de Química-Física)
Achieving efficient spatial modulation of phonon transmission is an essential step on the path to phononic circuits using "phonon currents". With their intrinsic and reconfigurable interfaces, domain walls (DWs), ferroelectrics are alluring candidates to be harnessed as dynamic heat modulators. [...]
