The effect of electron-phonon collision frequency, exchange-correlation potential, quantum term and degenerate pressure on the nature of solitary waves in a quantum semiconductor plasma is investigated. It is observed that the width of the solitary waves change with variation of different parameters for the GaAs semiconductor. A deformed Korteweg-de Vries equation is obtained for propagation of nonlinear waves in a quantum semiconductor plasma, and the effect of different parameters on the two-soliton solution of the equation are also presented.
