Abstract: A study of coupling of the lattice ion vibrations, with the electron waves in a piezoelectric semiconductor quantum plasma is presented. The nonlinearities have been studied and the solitons have been analyzed. The theory has been built using the quantum hydrodynamic (QHD) model, incorporating the effects of Fermi pressure, quantum Bohm and exchange correlation potentials. The dispersion relation for the coupling has been set up. A set of nonlinear evolution equations has been established using the two-time scale theory and soliton solution for coupled nonlinear evolution equations has been obtained using the modified quantum Zakharov equations. The solitons are found to have a cusp profile. It is also found that soliton's field amplitude increases significantly with particle density and coupling strength in piezoelectric semiconductor quantum plasma.
