The nonlinear propagation of acoustic waves in electron-hole semiconductor plasmas is studied. For this purpose, the reductive perturbation method is employed to the basic equations obtaining the Gardner equation. The latter has been solved using an extended homogeneous balance method to obtain a set of analytical solutions including solitary wave solution. The effects of different physical parameters on the nonlinear structures are examined.
