The influence of the surface migration of gold on the growth of silicon nanowires

Article Abstract:

The growth of silicon nanowires in conditions where all experimental parameters are in an extremely controlled environment is described. It is shown that gold diffusion during growth determines the length, shape and sidewall properties of nanowires, indicating that silicon nanowire growth is fundamentally limited by gold diffusion, smooth, long nanowires cannot be grown without eliminating gold migration.

Coaxial silicon nanowires as solar cells and nanoelectronic power sources

Article Abstract:

The development of p-type/intrinsic/n-type (p-i-n) coaxial silicon nanowire solar cells which could be applied to study the photo induced energy/charge transport and artificial photosynthesis is reported. The nanowire might also find general usage as elements for powering ultralow-power electronics and diverse nanosystems.

Silicon nanowires as efficient thermoelectric materials

Article Abstract:

The efficient thermoelectric performance exhibited by the single-component system of silicon nanowires is discussed. The high efficiency observed in such nanowires is found to be a result of the phonon effects.
