Reversible and Persistent Photoconductivity at the NdGaO3/SrTiO3 Conducting Interface

Umberto Scotti di Uccio, Carmela Aruta, Claudia Cantoni +10

The interface between the band gap insulators LaAlO3 and SrTiO3 is known to host a highly mobile two-dimensional electron gas. Here we report on the fabrication and characterizatio…
