The two-dimensional electron gas (2DEG) at oxides interfaces and surfaces has attracted large attention in physics and research due to its unique electronic properties and possible application in optoelectronics and nanoelectronics. The origin of 2DEGes at oxide interfaces has been attributed to the well known "polar catastrophe" mechanism. On the other hand, recently a 2DEG was also found on a clean SrTiO3(001) surface where it is formed due to oxygen vacancies. However, these 2DEG systems… Expand

Optically Controllable 2D Material/Complex Oxide Heterointerface
The 2D material/a‐STO heterostructure could be a potential platform for exploring new functional devices and experiences a dynamic evolution from negative to positive through tuning the light programming time. Expand


Creation and control of a two-dimensional electron liquid at the bare SrTiO3 surface.
It is shown that a similar two-dimensional electron gas, with an electron density as large as 8×10(13)  cm(-2), can be formed at the bare SrTiO(3) surface, and that the 2DEG density can be controlled through exposure of the surface to intense ultraviolet light. Expand
Two-dimensional electron gas with universal subbands at the surface of SrTiO3
It is shown, using angle-resolved photoemission spectroscopy, that there is a highly metallic universal 2DEG at the vacuum-cleaved surface of SrTiO3 (including the non-doped insulating material) independently of bulk carrier densities over more than seven decades. Expand
High mobility conduction at (110) and (111) LaAlO3/SrTiO3 interfaces
It is shown that epitaxial interfaces are not a prerequisite: conducting amorphous LaAlO3 and other oxides can also be prepared and open a new perspective both for materials research and for elucidating the ultimate microscopic mechanism of carrier doping. Expand
A high-mobility electron gas at the LaAlO3/SrTiO3 heterointerface
A model interface is examined between two insulating perovskite oxides—LaAlO3 and SrTiO3—in which the termination layer at the interface is controlled on an atomic scale, presenting a broad opportunity to tailor low-dimensional charge states by atomically engineered oxide heteroepitaxy. Expand

Electronic phase separation at the LaAlO₃/SrTiO₃ interface.
An EPS state is reported at the LaAlO(3)/SrTiO (3) interface, where the interface charges are separated into regions of a quasi-two-dimensional electron gas, a ferromagnetic phase, which persists above room temperature, and a diamagnetic/paramagnetic phase below 60 K. Expand
Why some interfaces cannot be sharp
A central goal of modern materials physics and nanoscience is the control of materials and their interfaces to atomic dimensions. For interfaces between polar and nonpolar layers, this goal isExpand
