Spin lifetimes of electrons injected into GaAs and GaN
The spin relaxation time of electrons in GaAs and GaN are determined with a model that includes momentum scattering by phonons and ionized impurities, and spin scattering by the Elliot-Yafet, D’yakonov-Perel, and BirAronov-Pikus mechanisms. Accurate bands generated using a long-range tight-binding Hamiltonian obtained from empirical pseudopotentials are used. The inferred temperature-dependence...
متن کاملTransport of energetic electrons into Saturn’s inner magnetosphere
[1] We present energetic electron data obtained by Cassini’s Magnetospheric Imaging Instrument in the inner magnetosphere of Saturn. We find here that inward transport and energization processes are consistent with conservation of the first two adiabatic invariants of motion. We model several injections near local midnight, one injection has a maximum energy of hundreds of keV, that are consist...
متن کاملSpin polarization of injected electrons.
LaBella et al. (1) claimed 92% spin polarization for electrons injected into gallium arsenide [GaAs(110)] from a Ni scanning tunneling microscope (STM) tip, which, they asserted, emitted 100% spin-polarized electrons. Such a claim, if substantiated, would constitute a development of great importance for the emerging field of spintronics: It would suggest that the field is rapidly closing in on ...
متن کاملEnergetic electrons associated with magnetic reconnection in the magnetic cloud boundary layer.
Here is reported in situ observation of energetic electrons (∼100-500 keV) associated with magnetic reconnection in the solar wind by the ACE and Wind spacecraft. The properties of this magnetic cloud driving reconnection and the associated energetic electron acceleration problem are discussed. Further analyses indicate that the electric field acceleration and Fermi-type mechanism are two funda...
متن کاملProduction of energetic electrons during magnetic reconnection.
The production of energetic electrons during magnetic reconnection is explored with full particle simulations and analytic analysis. Density cavities generated along separatrices bounding growing magnetic islands support parallel electric fields that act as plasma accelerators. Electrons because of their low mass are fast enough to make multiple passes through these acceleration cavities and ar...
