- Abstract
- Clusters of TiSi were formed in a polysilicon matrix by thermal annealing
of a Ti-Si multilayer structure. The silicide grain size was varied by
suitable thermal treatments. The DC electrical resistivity of the composite
material has been measured in the 4-500 K temperature range by van der Pauw
technique. Structural characterisation was performed by transmission
electron microscopy equipped with an electron energy loss spectrometer. The
dependence of resistivity on temperature indicated that at low temperature
the electric transport occurs by percolation through connected TiSi grains,
whilst at high temperature hopping between insulated grain dominates. The
volume fraction of percolating grains and the hopping probability has been
derived from the fit of the experimental data. (literal)
