By employing Sagdeev‟s pseudopotential technique large amplitude solitary waves are investigated in ultra-relativistic degenerate quantum plasma containing electrons and ions. The effect of relativistic degeneracy, quantum diffraction, ion temperature 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.
