Abstract :Improved techniques in semiconductor fabrication increased the interest in quantum wire structures, because of their opto-electronic device application possibilities. Many-body interactions among the electrons and holes in the wire lead to the band-gap renormalization insert ignore into journalissuearticles values(BGR);, which in turn affect the optical properties of the system. We study the BGR within the random-phase approximation incorporating the dynamical effects, and investigate the density dependence.Keywords : Turk J Phys, 23, 1999, 771 774 Turk J Phys, vol 23, iss 4
