We study low temperature electron mobility Β΅ n in a GaAs/Al x Ga 1-x As coupled double quantum well structure. Both the extreme barriers are Ξ΄-doped with Si so that the electrons diffuse into the adjacent wells forming two sheets of two-dimensional electron gas (2DEG) separated by a thin central bar
