in the preceding comment to account for the energy gap reported by us 1 in epitaxial graphene on 6H-SiC is unfounded. In our view, the effects of modulations on the lateral structure of graphene ...

polar textures in BaTiO 3 nanostructures is very promising for future applications. More information: Ibukun Olaniyan et al, Switchable topological polar states in epitaxial BaTiO3 nanoislands on ...
