Giant oscillating thermopower at oxide interfaces
Giant oscillating thermopower at oxide interfaces
Abstract Understanding the nature of charge carriers at the LaAlO 3 /SrTiO 3 interface is one of the major open issues in the full comprehension of the charge confinement phenomenon in oxide heterostructures. Here, we investigate thermopower to study the electronic structure in LaAlO 3 /SrTiO 3 at low temperature …
