The interplay of electronic reconstructions, lattice distortions, and surface oxygen vacancies in insulator-metal transition of LaAlO${}_3$/SrTiO${}_3$

Jun Zhou, Teguh Citra Asmara, Ming Yang +3

The mechanism responsible for the extraordinary interface conductivity of LaAlO${}_3$ on SrTiO${}_3$ and its insulator-metal transition remains controversial. Here, using density f…
