Strong electronic correlation

WebFeb 18, 2011 · We studied the effect of strong electron correlations on an oxide 2DEG by inserting a single atomic layer of R O ( R is La, Pr, Nd, Sm, or Y) into an epitaxial SrTiO 3 matrix using pulsed-laser deposition with atomic layer control. The R O layer donates electrons to the conduction band of SrTiO 3. WebMay 3, 2024 · It should be emphasized that strong correlation is not identical to strong interaction. For example, when electron–electron repulsions become very strong, the physics is often simply that...
