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. [...]

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. [...]
