Ferroelectric 180 degree walls are mechanically softer than the domains they separate
Christina Stefani, Louis Ponet, Konstantin Shapovalov +7
Domain walls are functionally different from the domains they separate, but little is known about their mechanical properties. Using scanning probe microscopy, we have measured the…
Liberation of slave modes inside domain walls in multiferroic Cu-Cl boracite
Peng Chen, Sergey Artyukhin
Domain walls (DWs), the two-dimensional boundaries between symmetry equivalent ferroic domains, are actively investigated due to their promise for novel logic and memory devices. M…
Unexpected Giant Microwave Conductivity in a Nominally Silent BiFeO3 Domain Wall
Yen-Lin Huang, Lu Zheng, Peng Chen +10
Nanoelectronic devices based on ferroelectric domain walls (DWs), such as memories, transistors, and rectifiers, have been demonstrated in recent years. Practical high-speed electr…
Activation of nominally silent domain wall-localized phonons from GHz to THz frequencies
Peng Chen, Louis Ponet, Keji Lai +2
Ferroelectric domain walls (DWs) are nanoscale topological defects that can be easily tailored to create nanoscale devices. Their excitations, recently discovered to be responsible…
