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…
