Role of Dynamic Jahn-Teller Distortions inNa2C60andNa2CsC60Studied by NMR

Large Pairing Jahn-Teller Distortions Around Divacancies in Crystalline Silicon

Ab initio atomic and electronic structures of neutral (V 0 2 ) and charged (V + 2 , V 2 , V 2 2 ) Si divacancies are investigated using bulk-terminated clusters with up to 320 Si atoms. For the rst time, the relaxed structures for V + 2 , V 0 2 , and V 2 are found to exhibit large pairing Jahn-Teller distortions consistent with electron paramagnetic resonance experiments. Atomic relaxations, Ja...

Evidence of dynamic Jahn-Teller distortions in two-dimensional crystalline molecular films

Jahn-Teller distortions and the supershell effect in metal nanowires.

A stability analysis of metal nanowires shows that a Jahn-Teller deformation breaking cylindrical symmetry can be energetically favorable, leading to stable nanowires with elliptic cross sections. The sequence of stable cylindrical and elliptical nanowires allows for a consistent interpretation of experimental conductance histograms for alkali metals, including both the electronic shell and sup...

Jahn-Teller distortions, cation ordering and octahedral tilting in perovskites.

In transition metal oxides, preferential occupation of specific d orbitals on the transition metal ion can lead to the development of a long-range ordered pattern of occupied orbitals. This phenomenon, referred to as orbital ordering, is usually observed indirectly from the cooperative Jahn-Teller distortions (CJTDs) that result as a consequence of the orbital ordering. This paper examines the ...
