The present work theoretically studies the possibility to hinder the formation of a "dead" layer at the interfaces in manganite superlattices. We showed that this goal can be reached by using alkaline-earth simple oxides as alternating layers in very thin superlattices. Indeed, such alternating layer promotes the contraction of manganite layers at the interfaces and $d_{x^2-y^2}$ preferred $e_g$ orbital occupancy, while Boltzman's transport calculations show an increase in conductivity. This result hold for different manganites, different alkaline-earth simple oxides as well as different thicknesses of the two layers. |
