Design of Mott and topological phases on buckled 3d-oxide honeycomb lattices
David Doennig, Santu Baidya, Warren E. Pickett +1
Perovskite bilayers with (111)-orientation combine a honeycomb lattice as a key feature with the strongly correlated, multiorbital nature of electrons in transition metal oxides. I…
Control of orbital reconstruction in (LaAlO)/(SrTiO)(001) quantum wells by strain and confinement
David Doennig, Rossitza Pentcheva
The diverse functionality emerging at oxide interfaces calls for a fundamental understanding of the mechanisms and control parameters of electronic reconstructions. Here, we explor…
Mott Electrons in an Artificial Graphenelike Crystal of Rare-Earth Nickelate
S. Middey, D. Meyers, D. Doennig +10
Deterministic control over the periodic geometrical arrangement of the constituent atoms is the backbone of the material properties, that along with the interactions define the ele…
Confinement-driven transitions between topological and Mott phases in (LaNiO3)/(LaAlO3)(111) superlattices
David Doennig, Warren E. Pickett, Rossitza Pentcheva
A set of broken symmetry two-dimensional ground states are predicted in (111)-oriented (LaNiO)/(LaAlO) (/) superlattices, based on density functional theory (…
Momentum-resolved electronic structure at a buried interface from soft x-ray standing-wave angle-resolved photoemission
A. X. Gray, J. Minár, L. Plucinski +19
Angle-resolved photoemission spectroscopy (ARPES) is a powerful technique for the study of electronic structure, but it lacks a direct ability to study buried interfaces between tw…
Massive symmetry breaking in LaAlO/SrTiO(111) quantum wells: a three-orbital, strongly correlated generalization of graphene
David Doennig, Warren E. Pickett, Rossitza Pentcheva
Density functional theory calculations with an on-site Coulomb repulsion term (GGA+U method) reveal competing ground states in (111) oriented (LaAlO)/(SrTiO) superl…
