Spintronics, or spin electronics, involves the study of active control and manipulation of spin
degrees of freedom in solid-state systems. This article reviews the current status of this …

After the first unequivocal demonstration of spin transport in graphene [Tombros et al.,
Nature (London) 448, 571–574 (2007)], surprisingly at room temperature, it was quickly …

The mesoscopic spin system formed by the 10 4–10 6 nuclear spins in a semiconductor
quantum dot offers a unique setting for the study of many-body spin physics in the …

Better sources of spin polarized electrons have been desired for many years. Some
pioneering experiments have been carried out at great difficulty with marginal sources, but …

Low-temperature electron-spin relaxation is studied by the optical orientation method in bulk
n-GaAs with donor concentrations from 10 14 cm− 3 to 5× 10 17 cm− 3. A peculiarity related …

In recent years, the physics community has experienced a revival of interest in spin effects in
solid state systems. On one hand, the solid state systems, particularly, semiconductors and …

Prospect of building electronic devices in which electron spins store and transport
information has revived interest in the spin relaxation of conduction electrons. Since spin …

We study the decoherence of a single electron spin in an isolated quantum dot induced by
hyperfine interaction with nuclei for times smaller than the nuclear spin relaxation time. The …

Spintronics is the ability of injecting, manipulating and detecting electron spins into solid
state systems. Molecular-electronics investigates the possibility of making electronic devices …

We demonstrate dynamical nuclear-spin polarization in the absence of an external magnetic
field by resonant circularly polarized optical excitation of a single electron or hole charged …
