TL;DR: In this paper, the authors discuss the constitution of atoms and molecules and propose a model of atoms, molecules, and their relations with atoms and atoms, which is based on the notion of the atom-and-molecular relationship.

TL;DR: In this paper, a generalization of the theory applicable to narrow degenerate electron bands is developed, based upon the notion that in the case of narrow bands the most important correlations are those between electrons on the same atom.
Abstract: In a previous paper a theory of correlation effects in narrow s -bands was described. In this paper a generalization of that theory applicable to narrow degenerate electron bands is developed. The theory is based upon the notion that in the case of narrow bands the most important correlations are those between electrons on the same atom. The solution obtained has the important property of going over into the ordinary band theory solution in the appropriate limit (no interaction) and the exact atomic (Heitler-London) solution in the opposite limit (zero band-width). In order to elucidate the general properties of the solution some simplified models are discussed, and the more elementary implications of the theory when applied to the d -bands of transition metals are indicated. A physical interpretation of the results of the theory is given; the physical picture which emerges is found to be closely related to a theory discussed earlier by Van Vleck.

TL;DR: Just one atom thick, this two-dimensional semiconductor does not resemble any known material as mentioned in this paper, and it has been shown that it can be used as a semiconductor for medical applications.
