  Slow dynamics in an amorphous quasi-two-dimensional complex plasma, comprised
of microparticles of two different sizes, was studied experimentally. The
motion of individual particles was observed using video microscopy, and the
self-part of the intermediate scattering function as well as the mean-squared
particle displacement was calculated. The long-time structural relaxation
reveals the characteristic behavior near the glass transition. Our results
suggest that binary complex plasmas can be an excellent model system to study
slow dynamics in classical supercooled fluids.
