Electrical expression of spin accumulation in ferromagnet/semiconductor structures
L. Cywinski, H. Dery, P. Dalal +1
We treat the spin injection and extraction via a ferromagnetic metal/semiconductor Schottky barrier as a quantum scattering problem. This enables the theory to explain a number of…

Ultrafast demagnetization in the sp-d model: a theoretical study
L. Cywinski, L. J. Sham
We propose and analyze a theoretical model of ultrafast light-induced magnetization dynamics in systems of localized spins that are coupled to carriers' spins by sp-d exchange inte…

Photoluminescence and spectral switching of single CdSe/ZnS colloidal nanocrystals in poly(methyl methacrylate)
Y. M. Shen, L. Pang, Y. Fainman +4
Emission from single CdSe nanocrystals in PMMA was investigated. A fraction of the nanocrystals exhibiting switching between two energy states, which have similar total intensities…
