We　investigate　the　nonlinear　stability　of　the　superposition　of　a　viscous　contact　wave　and　two　rarefaction　waves　for　a　one-dimensional　(1D)　bipolar　Vlasov　Poisson　Boltzmann　(VPB)　system,　which　can　be　used　to　describe　the　transportation　of　charged　particles　under　the　additional　electrostatic　potential　force.　Based　on　a　new　micro-macro　type　of　decomposition　around　the　local　Maxwellian　related　to　the　bipolar　VPB　system　in　the　previous　work　[H.-L.　Li,　Y.　Wang,　T.　Yang,　and　M.-Y.　Zhong,　Arch.　Ration.　Mech.　Anal.,　228　(2018),　pp.　39-127],　we　prove　that　the　superposition　of　a　viscous　contact　wave　and　two　rarefaction　waves　is　time-asymptotically　stable　to　the　1D　bipolar　VPB　system　under　some　smallness　conditions　on　the　initial　perturbations　and　wave　strength,　which　implies　that　this　typical　superposition　wave　pattern　is　nonlinearly　stable　under　the　combined　effects　of　the　binary　collisions,　the　electrostatic　potential　force,　and　the　mutual　interactions　of　different　charged　particles.　This　is　the　first　result　about　the　nonlinear　stability　of　the　combination　of　two　different　wave　patterns　for　the　VPB　system.
