Current transport in semiconductor nanowires with built-in barriers based on a 1D transfer matrix calculation
(2008)A one dimensional (1D) transfer matrix calculation of current transport in semiconductor nanowires with built-in barriers is described within the effective mass approximation by taking into account (i) the quantum confinement ...

Highly efficient spin filtering of ballistic electrons in hybrid spin valve/semiconductor structures
(2004)The highly efficient spin filtering of ballistic electrons in hybrid spin valve/semiconductor (SC) structures was discussed. It was found that the photocurrent was dependent on the relative alignment of the light helicity ...

InAs quantum dots grown by molecular beam epitaxy on GaAs (211)B polar substrates
(2006)InAs nanostructures were grown by molecular beam epitaxy on GaAs (211)B at temperatures between 400-530 °C and growth rates that were varied between 0.1 to 0.02 mono-layers (ML) per second. For temperatures up to 500 °C ...
