We prove the existence of a ground state positive solution of Schrödinger–Poisson systems in the plane of the form
, $\gamma,b>0$
and the potential $V$
is assumed to be positive and unbounded at infinity. On the potential we do not require any symmetry or periodicity assumption, and it is not supposed it has a limit at infinity. We approach the problem by variational methods, using a variant of the mountain pass theorem and the Cerami compactness condition.
