Atomistic Theory of Coherent Spin Transfer between Molecularly Bridged Quantum Dots
Joshua Schrier, K. Birgitta Whaley
Time-resolved Faradary rotation experiments have demonstrated coherent transfer of electron spin between CdSe colloidal quantum dots coupled by conjugated molecules. We employ here…
Thomas-Fermi Theory of the Hyperfine Constants of Endohedral Fullerene Atoms
Joshua Schrier, K. Birgitta Whaley
We present a modified Thomas-Fermi theory that describes the increase of the hyperfine coupling constants of endohedrally enclosed atoms. We use the March boundary conditions corre…
Electronic transport, structure, and energetics of endohedral Gd@C82 metallofullerenes
Laxmidhar Senapati, Joshua Schrier, K. Birgitta Whaley
Electronic structure and transport properties of the fullerene C and the metallofullerene Gd@C are investigated with density functional theory and the Landauer-Buttik…
A Simple Model for Magnetization Ratios in Doped Nanocrystals
Joshua Schrier, K. Birgitta Whaley
Recent experiments on Mn-doped ZnS nanocrystals have shown unusual magnetization properties. We describe a nearest-neighbor Heisenberg exchange model for calculating the magnetizat…
Tight-binding g-Factor Calculations of CdSe Nanostructures
Joshua Schrier, K. Birgitta Whaley
The Lande g-factors for CdSe quantum dots and rods are investigated within the framework of the semiempirical tight-binding method. We describe methods for treating both the n-dope…
