Arbitrary amplitude solitary waves are investigated in finite temperature quantum plasma containing electrons and ions by employing Sagdeev’s pseudopotential technique. The effect of electron degeneracy, ion temperature, quantum diffraction has important contribution in determining the nature of pseudopotential well. They also determine the formation and properties of ion acoustic waves in this two-component electron-ion dense quantum plasma.
