Tunable vertical ferroelectricity and domain walls by interlayer sliding in β-ZrI2
Abstract Vertical ferroelectricity where a net dipole moment appears as a result of in-plane ionic displacements has gained enormous attention following its discovery in transition metal dichalcogenides. Based on first-principles calculations, we report on the evidence of robust vertical ferroelectr...
