In this paper, we study the following linearly coupled system , where ε > 0 is a small parameter, Pi(x) are positive potentials, and λij = λji > 0 (i ≠ j) are coupling constants for i, j = 1, …, N. We investigate the effect of potentials to the structure of the solutions. More precisely, we construct multi-spikes solutions concentrating near the local maximum point of Pi(x). When , , the components have spikes clustering at the same point as ε → 0+. When , the components have spikes clustering at the different points as ε → 0+.
