Electrical determination of the spin relaxation time of photoexcited electrons in GaAs
(2010)Spin-dependent transport for photoexcited electrons in an epitaxial Fe/GaAs interface was characterized from 5 to 300 K. The presence of spin-dependent transport was confirmed at all the measured temperatures and the spin ...

Speed selection mechanism for propagating fronts in reaction-diffusion systems with multiple fields
(2002)We introduce a speed selection mechanism for front propagation in reaction-diffusion systems with multiple fields. This mechanism applies to pulled and pushed fronts alike, and operates by restricting the fields to large ...

Transient photoinduced absorption in ultrathin as-grown nanocrystalline silicon films
(2008)We have studied ultrafast carrier dynamics in nanocrystalline silicon films with thickness of a few nanometers where boundary-related states and quantum confinement play an important role. Transient non-degenerated ...
