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…

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…
