Piezoelectric domain walls in van der Waals antiferroelectric CuInP2Se6
Domain walls in van der Waals layered ferrielectric CuInP2Se6 exhibit piezoelectric response. This striking departure from traditional ferroelectric behavior is ascribed to a partially polarized antiferroelectric state, where the domain wall separates coexisting regions of ferrielectric and antiferr...

Sumario: | Domain walls in van der Waals layered ferrielectric CuInP2Se6 exhibit piezoelectric response. This striking departure from traditional ferroelectric behavior is ascribed to a partially polarized antiferroelectric state, where the domain wall separates coexisting regions of ferrielectric and antiferroelectric phases. |
