Abstract

The emission spectra of plasmas produced near the surface of silicon and sulphur samples and their mixtures by nanosecond and millisecond laser pulses are studied in a broad range of pressures of buffer gases. The percolation dependences are obtained for composite Si--S, Si--SiO2, and SiO2--S targets. It is found that experimental percolation thresholds coincide with the typical threshold for three-dimensional continual percolation.
