Modulation of superconducting transition temperature in LaAlO${}_3$/SrTiO${}_3$ by SrTiO${}_3$ structural domains

Hilary Noad, Pascal Wittlich, Jochen Mannhart +1

The tetragonal domain structure in SrTiO${}_3$ (STO) is known to modulate the normal-state carrier density in LaAlO${}_3$/SrTiO${}_3$ (LAO/STO) heterostructures, among other electr…
