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...

WebJan 5, 2024 · In the most expanded Cs 3 C 60 films, the strong electronic correlation U/W and JT effect lead to the opening of a Mott insulating gap. Thus, 9 ML Cs 3 C 60 film is a MJTI . With reduced A + cation size or lattice constant, electron delocalizes as U/W decreases, and metallicity as well as a superconductivity is realized in 9 ML K 3 C 60 and … WebFeb 22, 2008 · Most electron transfer (ET) theories for molecular systems, and much MJ modeling, ignore the effect of electronic correlations except in a mean-field approximation. Even within the latter, different molecular charge states will have different energy levels. WebJul 14, 2024 · Strong electron–electron correlations can give rise to surprising co-operative phenomena, typically very hard to explain and even harder to predict. Paradigmatic examples are high-temperature superconductivity in the cuprates, other types of unconventional superconductivity, Mott insulating or heavy fermion behavior, spin and orbital ordering ... ruthenium red electron microscopy
