Modulation on the electrical and optical properties of Na and Rh co-doped Ruddlesden-Popper layered Ca₃Ti₂O₇

Layered perovskite Ca_2.91Na_0.09Ti_2-xRh_xO₇ (x = 0.00, 0.02, 0.04, 0.06) were synthesized by a conventional solid-state reaction. Room temperature ferroelectricity has been confirmed. The remanent polarization incr...
