We　consider　the　periodic　problem　for　2-fluid　nonisentropic　Euler-Poisson　equations　in　semiconductor.　By　choosing　a　suitable　symmetrizers　and　using　an　induction　argument　on　the　order　of　the　time-space　derivatives　of　solutions　in　energy　estimates,　we　obtain　the　global　stability　of　solutions　with　exponential　decay　in　time　near　the　nonconstant　steady-states　for　2-fluid　nonisentropic　Euler-Poisson　equations.　This　improves　the　results　obtained　for　models　with　temperature　diffusion　terms　by　using　the　pressure　functions　p(nu)　in　place　of　the　unknown　variables　densities　n(nu).
