In recent years, a unique type of domain walls, i.e., the sawtooth-shaped domain walls, has been observed in BiFeO3 and PbTiO3. Here, we build a minimal model to reveal the origin of these sawtooth-shaped domain walls. Incorporating this model into Monte Carlo simulations shows that (i) the competition between the long-range Coulomb interaction (due to bound charges) and short-range interaction (due to opposite dipoles) is responsible for the formation of these peculiar domain walls and (ii) their relative strength is critical in determining the periodicity of these sawtooth-shaped domain walls. Necessary conditions to form such domain walls are also discussed.}, cin = {ER-C-1}, ddc = {530}, cid = {I:(DE-Juel1)ER-C-1-20170209}, pnm = {143 - Controlling Configuration-Based Phenomena (POF3-143)}, pid = {G:(DE-HGF)POF3-143}, typ = {PUB:(DE-HGF)16}, UT = {WOS:000515628700001}, doi = {10.1103/PhysRevB.101.060103}, url = {https://juser.fz-juelich.de/record/878254}, }
