Spontaneous Structural Distortion and Quasi‐One‐Dimensional Quantum Confinement in a Single‐Phase Compound. (29th November 2012) - Wang, Zhongchang
Abstract Oxide heterointerfaces often trigger unusual electronic properties that are absent in respective bulks. Here, direct evidence is offered for spontaneously assembled local structural distortions in a single‐phase bulk, which confine electrons to within an atomic layer with notable orbital reconstruction and coupling, close the forbidden band, induce a ferromagnetic ordering, and give rise to a strongly anisotropic, spin‐polarized quasi‐one‐dimensional electron gas.
