Artificial two-dimensional polar metal at room temperature

Artificial two-dimensional polar metal at room temperature

Materials that combine metallic behaviour with stable electric polarization are scarce despite being proposed in the 1960s. Here the authors engineer a perovskite heterostructure where 2D polar metallic behavior coexists with built-in electric polarization from the displacement of B-site titanium ca...
