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…
Electron transfer and ionic displacements at the origin of the 2D electron gas at the LAO/STO interface: Direct measurements with atomic-column spatial resolution
C. Cantoni, J. Gazquez, F. Miletto Granozio +8
The discovery that the interface between two band gap insulators LaAlO3 and SrTiO3 is highly conducting has raised an enormous interest in the field of oxide electronics. The LAlO3…
Observation of a two-dimensional electron gas at the surface of annealed SrTiO3 single crystals by scanning tunneling spectroscopy
R. Di Capua, M. Radovic, G. M. De Luca +7
Scanning tunneling spectroscopy suggests the formation of a two dimensional electron gas (2DEG) on the TiO2 terminated surface of undoped SrTiO3 single crystals annealed at tempera…
Critical influence of target-to-substrate distance on conductive properties of LaGaO3/SrTiO3 interfaces deposited at 10-1 mbar oxygen pressure
Carmela Aruta, Salvarore Amoruso, Giovanni Ausanio +8
We investigate pulsed laser deposition of LaGaO3/SrTiO3 at 10-1 mbar oxygen background pressure, demonstrating the critical effect of the target-to-substrate distance, dTS, on the…
