We consider the following singularly perturbed Schrödinger equation where N≥3$N\ge 3$, 94a5c6f55cce50b4927a3be4f7d3" title="Click to view the MathML source">V$V$ is a nonnegative continuous potential and the nonlinear term b20afa69e05ef7d7bffdfa48bb3b0" title="Click to view the MathML source">f$f$ is of critical growth. In this paper, with the help of a truncation approach, we prove that if 94a5c6f55cce50b4927a3be4f7d3" title="Click to view the MathML source">V$V$ has a positive local minimum, then for small b4e084fdfe6076479ecdb7" title="Click to view the MathML source">ε$\epsilon$ the problem admits positive solutions which concentrate at an isolated component of positive local minimum points of 94a5c6f55cce50b4927a3be4f7d3" title="Click to view the MathML source">V$V$ as ε→0$\epsilon \to 0$. In particular, the potential 94a5c6f55cce50b4927a3be4f7d3" title="Click to view the MathML source">V$V$ is allowed to be either compactly supported   or decay faster than ∣x∣⁻²$\mid x{\mid }^{-2}$ at infinity. Moreover, a general nonlinearity b20afa69e05ef7d7bffdfa48bb3b0" title="Click to view the MathML source">f$f$ is involved, i.e., the monotonicity   of f(s)/s$f\left(s\right)/s$ and the Ambrosetti–Rabinowitz condition are not required.
