Sub-nm2 ferroelectric domains via charged 180 degree walls in ZrO2
Nashrah Afroze, Hamoon Fahrvandi, Guodong Ren +31
Flat phonon bands in fluorite ferroelectrics (HfO2 or ZrO2) shrink polar domains laterally to an irreducible half-unit-cell width (0.27 nm) within which the vertical arrangement of…

Antiferroelectric negative capacitance from a structural phase transition in zirconia
Michael Hoffmann, Zheng Wang, Nujhat Tasneem +20
Crystalline materials with broken inversion symmetry can exhibit a spontaneous electric polarization, which originates from a microscopic electric dipole moment. Long-range polar o…
