Arbitrary amplitude solitary waves are investigated in weakly relativistic degenerate quantum plasma containing electrons and ions by employing Sagdeev’s pseudopotential approach. It is found that relativistic degeneracy, ion-to electron Fermi temperature ratio and quantum diffraction have significant contributions in determining the nature of pseudopotential well as well as the formation and properties of ion acoustic solitary wave structures in a two-component electron-ion dense quantum plasma.
