The structure appearance in exciton density distribution in semiconductor double quantum well with transverse electric field applied is studied, in the case when the metal electrode contains a round window. It is suggested that there is exciton condensed phase, free energy of which can be described by phenomenological Landau model. For the exciton density determination the traditional theory of phase transitions was used generated for the case of the finite exciton lifetime, a presence of the pumping and nonhomogenity of the system. It is shown that at high exciton density the different types of structures appear: periodic distribution of exciton condensed phase islands or condensed phase rings. The behavior of the structures depending on the pumping, the window size and temperature is analyzed. The obtained results are agreed with experimental data.
