Erratum: “Controllable-permittivity and high-tunability of Ba0.5Sr0.5TiO3/MgO based ceramics by composite configuration” [Appl. Phys. Lett. 102, 142907 (2013)]

was published online on 9 April 2013 with an error in Fig. 2. In the published manuscript, in the Fig. 2, ? and// should exchange with each other. The corrected plot of Fig. 2 is shown below. So the corrected description of Fig. 2 is “At20 C, permittivity values of pure BST50, 2-2-//, 3-0, and 2-2-? samples are 2000, 1460, 1044, and 88, respectively.”
