The correlation between luminescence and transport in systems of silicon nano-crystallites

Abstract

The transport in a system of silicon nanocrystals embedded in an insulating matrix is shown to behave as in granular metals. The percolation aspect of this transport was demonstrated clearly in our work, while the tunneling-Coulomb blockade aspects that were suggested by others, are indirectly manifested by the relation between the photoluminescence and the transport properties.
