Persistent photoconductivity in 2-dimensional electron gases at different oxide interfaces

Emiliano Di Gennaro, Umberto Scotti di Uccio, Carmela Aruta +10

We report on the transport characterization in dark and under light irradiation of three different interfaces: LaAlO3/SrTiO3, LaGaO3/SrTiO3, and the novel NdGaO3/SrTiO3 heterostruc…
