T
he growth rate of the dust-acoustic surface wave in the semi-
bounded 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 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 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 surface wave is compared with that of bulk wave
for various physical parameters
Biography
Young Dae Jung received his B.S. degree in physics in 1984 from Hanyang
University, Seoul, South Korea, and the PhD degree in theoretical physics in 1990
from the University of California, San Diego. After his PhD, he held the National
academy of sciences/National research council research fellowship at NASA/
Marshall Space Flight Center. Since 1992, he has been at Hanyang University,
Ansan, South Korea, where he is Professor of Applied Physics. His research deals
with theoretical atomic physics, plasma physics, and astrophysics. At various
times, he has been associated with NASA/Marshall Space Flight Center, U.S.A.
and National Institute of Fusion Science, Japan. In addition, he held the visiting
professorship at National Institute of Fusion Science in 2008. He is a member of the
Korean Physical Society and the American Physical Society.
