Journal ArticleDOI
Designer magnetic superatoms
J. Ulises Reveles,Peneé A. Clayborne,Arthur C. Reber,Shiv N. Khanna,Kalpataru Pradhan,Prasenjit Sen,Mark R. Pederson +6 more
TL;DR: This work proposes a framework for magnetic superatoms by invoking systems that have both localized and delocalized electronic states, in which localized electrons stabilize magnetic moments and filled nearly-free electron shells lead to stable species.
Journal ArticleDOI
Electronic structure and ground states of transition metals encapsulated in a Si 12 hexagonal prism cage
Prasenjit Sen,Lubos Mitas +1 more
TL;DR: In this paper, the electronic structure of recently discovered clusters with an encapsulated transition metal (TM) atom in a hexagonal prism cage was investigated and it was shown that the cage geometry is remarkably stable regardless of the type of doping TM atom from $3d,4d,$ and $5d$ series.
Journal ArticleDOI
Hund’s rule in superatoms with transition metal impurities
Victor M. Medel,J. U. Reveles,Shiv N. Khanna,Vikas Chauhan,Prasenjit Sen,A. Welford Castleman +5 more
TL;DR: The possibility of enhancing exchange splitting in superatom shells via a composite cluster of a central transition metal and surrounding nearly free electron metal atoms is demonstrated.
Journal ArticleDOI
Density Functional Investigation of Structure and Stability of Gen and GenNi (n = 1−20) Clusters: Validity of the Electron Counting Rule
TL;DR: It is found that in clusters containing more than 8 Ge atoms the Ni atom is absorbed endohedrally in the Ge cage, and there is a sharp drop in IP as the valence electron count increases from 20 to 21, in agreement with predictions of shell models.
Journal ArticleDOI
Pentagonal nanowires: A first-principles study of the atomic and electronic structure
TL;DR: In this article, the authors performed an extensive first-principles study of nanowires in various pentagonal structures by using pseudopotential plane wave method within the density functional theory.
