  • Abstract
    On a system of silicon nanocrystals we explain and demonstrate the importance of measuring THz photoconductivity spectra in a wide range of excitation densities. This allows one to independently characterize contributions of percolated and non-percolated parts of the sample to the total photoconductivity.
