Abstract
The present disclosure is related to a dielectric layer comprising a rare-earth aluminate (REAlOwith 0<x<2) and having a perovskite crystalline structure, wherein the rare-earth aluminate comprises a rare-earth element having an atomic number higher than or equal to 63 and lower than or equal to 71. The disclosure also relates to method of manufacturing of a dielectric stack and a dielectric stack comprising said rare-earth aluminate dielectric layer and further comprising a template stack comprising at least an upper template layer, wherein the upper template layer has a perovskite structure, and wherein the upper template layer is underlying and in contact with the rare-earth aluminate dielectric layer. In a preferred embodiment the dielectric stack further comprises a lower template layer having a crystalline structure, wherein the lower template layer is underlying and in contact with the upper template layer.
