Abstract
The growth rate of the dust-acoustic surface wave in the semi-infinite complex plasma with an ion streaming passing through the plasma at rest is analytically derived. We have adopted the Lorentzian distribution for electrons to investigate the nonthermal property of a plasma on the growth rate. We find that the growth rate of the surface wave increases as the wave number increases, and it is always larger than that of the bulk wave, especially in the realm of large wave numbers. The nonthermal effect of Lorentzian electrons in the high-energy tail is found to enhance the growth rate. It is also found that the density and speed of streaming ion would increase the growth rate. The growth rate of the surface wave is compared to that of the bulk wave for various physical parameters. Published by AIP Publishing.
