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…
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…
Pulsed laser deposition of SrTiO3/LaGaO3 and SrTiO3/LaAlO3: plasma plume effects
C. Aruta, S. Amoruso, R. Bruzzese +4
Pulsed laser deposition of SrTiO3/LaGaO3 and SrTiO3/LaAlO3 interfaces has been analyzed with a focus on the kinetic energy of the ablated species. LaGaO3 and LaAlO3 plasma plumes w…
Magnetic properties of pseudomorphic epitaxial films of Pr_{0.7}Ca_{0.3}MnO_3 under different biaxial tensile stresses
A. Geddo Lehmann, F. Congiu, N. Lampis +4
In order to analyse the effect of strain on the magnetic properties of narrow-band manganites, the temperature and field dependent susceptibilities of about 8.5 nm thick epitaxial…
Conducting interfaces between band insulating oxides: the LaGaO3/SrTiO3
Paolo Perna, Davide Maccariello, Milan Radovic +9
We show that the growth of the heterostructure LaGaO3/SrTiO3 yields the formation of a highly conductive interface. Our samples were carefully analyzed by high resolution electron…
Blue luminescence of SrTiO3 under intense optical excitation
A. Rubano, D. Paparo, F. Miletto +2
The blue-green photoluminescence emitted by pure and electron-doped strontium titanate under intense pulsed near-ultraviolet excitation is studied experimentally, as a function of…
