Atomic-level direct imaging for Cu(I) multiple occupations and migration in 2D ferroelectric CuInP2S6
Abstract CuInP2S6 (CIPS) is an emerging 2D ferroelectric material known for disrupting spatial inversion symmetry due to Cu(I) position switching. Its ferroelectricity strongly relies on the Cu(I) atom/ion occupation ordering and dynamics. Nevertheless, the accurate Cu(I) occupations and correlated...
