A two-dimensional electron gas at the (001) surface of ferromagnetic EuTiO(001)
R. Di Capua, M. Verma, M. Radovic +10
Studies on oxide quasi-two dimensional electron gas (q2DEG) have been a playground for the discovery of novel and sometimes unexpected phenomena, like the reported magnetism at the…
Dynamics of the photoinduced insulator-to-metal transition in a nickelate film
Vincent Esposito, Laurenz Rettig, Elisabeth M. Bothschafter +24
The control of materials properties with light is a promising approach towards the realization of faster and smaller electronic devices. With phases that can be controlled via stra…
Observation of Wannier-Stark localization at the surface of BaTiO films by photoemission
Stefan Muff, Nicolas Pilet, Mauro Fanciulli +7
Observation of Bloch oscillations and Wannier-Stark localization of charge carriers is typically impossible in single-crystals, because an electric field higher than the breakdown…
Observation of a two-dimensional electron gas at CaTiO film surfaces
Stefan Muff, Mauro Fanciulli, Andrew P. Weber +6
The two-dimensional electron gas at the surface of titanates gathered attention due to its potential to replace conventional silicon based semiconductors in the future. In this stu…
Atomically precise lateral modulation of a two-dimensional electron liquid in anatase TiO2 thin films
Z. Wang, Z. Zhong, S. McKeown Walker +12
Engineering the electronic band structure of two-dimensional electron liquids (2DELs) confined at the surface or interface of transition metal oxides is key to unlocking their full…
Observation of Dirac-like band dispersion in LaAgSb
X. Shi, P. Richard, Kefeng Wang +10
We present a combined angle-resolved photoemission spectroscopy (ARPES) and first-principles calculations study of the electronic structure of LaAgSb in the entire first Brillo…
Revisiting the vortex-core tunnelling spectroscopy in YBaCuO
Jens Bruér, Ivan Maggio-Aprile, Nathan Jenkins +5
The observation by scanning tunnelling spectroscopy (STS) of Abrikosov vortex cores in the high-temperature superconductor YBaCuO (Y123) has revealed a robust pair…
Tailoring the nature and strength of electron-phonon interactions in the SrTiO(001) two-dimensional electron liquid
Z. Wang, S. McKeown Walker, A. Tamai +20
Surfaces and interfaces offer new possibilities for tailoring the many-body interactions that dominate the electrical and thermal properties of transition metal oxides. Here, we us…
Growth and characterization of conducting LaAlO3/EuTiO3/SrTiO3 het-erostructures
G. M. De Luca, R. Di Capua, E. Di Gennaro +9
We studied the structural, magnetic and transport properties of LaAlO3/EuTiO3/SrTiO3 heterostructures grown by Pulsed Laser Deposition. The samples have been characterized in-situ…
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…
In-situ Investigation of the Early Stage of TiO2 epitaxy on (001) SrTiO3
M. Radovic, M. Salluzzo, Z. Ristic +4
We report on a systematic study of the growth of epitaxial TiO2 films deposited by pulsed laser deposition on Ti-terminated (001) SrTiO3 single crystals. By using in-situ reflectio…
Polar catastrophe and electronic reconstructions at the LaAlO3/SrTiO3 interface: evidence from optical second harmonic generation
A. Savoia, D. Paparo, P. Perna +8
The so-called "polar catastrophe", a sudden electronic reconstruction taking place to compensate for the interfacial ionic polar discontinuity, is currently considered as a likely…
