Experimental verification of orbital engineering at the atomic scale: charge transfer and symmetry breaking in nickelate heterostructures

Autor: Phillips, Patrick J., Longo, Paolo, Georgescu, Alexandru B., Okunishi, Eiji, Rui, Xue, Disa, Ankit S., Walker, Fred, Ismail-Beigi, Sohrab, Ahn, Charles H., Klie, Robert F.

Publikováno v: Phys. Rev. B 95, 205131 (2017)

Epitaxial strain, layer confinement and inversion symmetry breaking have emerged as powerful new approaches to control the electronic and atomic-scale structural properties in complex metal oxides. Nickelate heterostructures, based on RENiO$_3$, wher

We determine the surface reconstruction of SrTiO3 used to achieve superconducting FeSe films in experiments, which is different from the 1x1 TiO2 terminated SrTiO3 assumed by most previous theoretical studies. In particular, we identify the existence

Oxide 2D electron gases as a route for high carrier densities on (001) Si

Autor: Kornblum, Lior, Jin, Eric N., Kumah, Divine P., Ernst, Alexis T., Broadbridge, Christine C., Ahn, Charles H., Walker, Fred J.

Two dimensional electron gases (2DEGs) formed at the interfaces of oxide heterostructures draw considerable interest owing to their unique physics and potential applications. Growing such heterostructures on conventional semiconductors has the potent

Synthesis of SnTe Nanoplates with {100} and {111} Surfaces

Autor: Shen, Jie, Jung, Yeonwoong, Disa, Ankit S., Walker, Fred J., Ahn, Charles H., Cha, Judy J.

Publikováno v: Nano letters 14 (7), 4183-4188, 2014

SnTe is a topological crystalline insulator that possesses spin-polarized, Dirac-dispersive surface states protected by crystal symmetry. Multiple surface states exist on the {100}, {110}, and {111} surfaces of SnTe, with the band structure of surfac
