Ferroelectricity and topological vortices from molecular ordering in metal-organic frameworks
Francesco Foggetti, Alessandro Stroppa, Sergey Artyukhin
Metal-organic frameworks comprehend a wide class of hybrid organic-inorganic materials with general structure ABX, with and being organic molecules and B a metal ca…
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…
First-principles theory of giant Rashba-like spin-splitting in bulk ferroelectrics
Louis Ponet, Sergey Artyukhin
Recently large Rashba-like spin splitting has been observed in certain bulk ferroelectrics. In contrast with the relativistic Rashba effect, the chiral spin texture and large spin-…
