High-k dielectric material
WebThe thinnest layered nanolaminate ( tL = 6 Å) showed the strongest dielectric constant εr ∼ 60 under a small signal ac electric field of ∼50 kV cm −1; this is the highest εr so far observed in HfO 2 –ZrO 2 thin films. This behavior was attributed to the formation of an MPB near FE/AFE interfaces.
