Abstract. We are concerned with the following Schrödinger-Poisson equation with critical nonlinearity:

-ε2Δu + V(x)u + ψu = λ|u|p-2u + |u|4u in R3,
-ε2Δψ = u2 in R3, u > 0, uH1(R3),

where ε > 0 is a small positive parameter, λ > 0, 3 < p ≤ 4. Under certain assumptions on the potential V, we construct a family of positive solutions uεH1(R3) which concentrates around a local minimum of V as ε → 0. Subcritical growth Schrödinger-Poisson equation

-ε2Δu + V(x)u + ψu = f(u) in R3,
-ε2Δψ = u2 in R3, u > 0, uH1(R3),

has been studied extensively, where the assumption for f(u) is that f(u) ∼ |u|p-2u with 4 < p < 6 and satisfies the Ambrosetti-Rabinowitz condition which forces the boundedness of any Palais-Smale sequence of the corresponding energy functional of the equation. The more difficult critical case is studied in this paper. As g(u) := λ|u|p-2u + |u|4u with 3 < p ≤ 4 does not satisfy the Ambrosetti-Rabinowitz condition (∃ μ > 4, 0 < μ0ug(s)dsg(u)u), the boundedness of Palais-Smale sequence becomes a major difficulty in proving the existence of a positive solution. Also, the fact that the function g(s)/s3 is not increasing for s > 0 prevents us from using the Nehari manifold directly as usual. The main result we obtained in this paper is new.
