Imaging and Control of Ferromagnetism in a Polar Antiferromagnet

X. Renshaw Wang, C. J. Li, W. M. Lü +10

Atomically sharp oxide heterostructures often exhibit unusual physical properties that are absent in the constituent bulk materials. The interplay between electrostatic boundary co…

Bandgap Controlling of the Oxygen-Vacancy-Induced Two-Dimensional Electron Gas in SrTiO3

Z. Q. Liu, W. Lu, S. W. Zeng +16

We report very large bandgap enhancement in SrTiO3 (STO) films (fabricated by pulsed laser deposition below 800 °C), which can be up to 20% greater than the bulk value, depending o…

Dominant role of oxygen vacancies in electrical properties of unannealed LaAlO3/SrTiO3 interfaces

Z. Q. Liu, L. Sun, Z. Huang +6

We report that in unannealed LaAlO3/SrTiO3 (LAO/STO) heterostructures the critical thickness for the appearance of the two-dimensional electron gas can be less than 4 unit cell (uc…

The Conducting Channel at the LaAlO/SrTiO Interface

Z. Huang, X. Renshaw Wang, Z. Q. Liu +10

Localization of electrons in the two-dimensional electron gas at the LaAlO/SrTiO interface is investigated by varying the channel thickness in order to establish the nature…

Origin of the two-dimensional electron gas at LaAlO3/SrTiO3 interfaces: The role of oxygen vacancies and electronic reconstruction

Z. Q. Liu, C. J. Li, W. M. Lü +10

The relative importance of atomic defects and electron transfer in explaining conductivity at the crystalline LaAlO3/SrTiO3 interface has been a topic of debate. Metallic interface…

Unexpected Anisotropic Two Dimensional Electron Gas at the LaAlO3/SrTiO3 (110) Interface

A. Annadi, X. Wang, K. Gopinadhan +17

The observation of a two dimensional electron gas (2DEG) (1, 2), superconductivity (3, 4), magnetic effects (5) and electronic phase separation (6-8) at the interfaces of insulatin…
