abstract = {Excellent thermal stability with high energy storage
density in ultra-wide range of temperatures is the extremely
important property of capacitors for applications in cold
polar regions, extreme altitudes and high temperature
regions. Here, we report on designing and preparing the
BaZr0.15Ti0.85O3/BaZr0.35Ti0.65O3 (BZT15/BZT35) multilayer
thin film capacitors. Under a given total thickness, the
energy storage performances of the multilayer films can be
optimized by controlling the number of interfaces. For the
capacitor with an optimum period number N = 6, the
markedly enhanced breakdown strength and large dielectric
constant are achieved, which leads to a giant energy storage
density (Wre) of ~83.9 J/cm3 with the efficiency (η) of
$~78.4\%$ and a superior power density of 1.47 MW/cm3 at
room temperature. Moreover, the N = 6 multilayer
capacitor also exhibits ultra-stable Wre of 69.1 J/cm3
(efficiency: $84.9\%)$ to 63.2 J/cm3 (efficiency:
$66.9\%)$ from − 100 °C to 200 °C and a good
reliability in Wre and η even after 106 cycles at
200 °C. The excellent performances demonstrate that the
multilayer films are a promising material system to meet the
wide requirements of future applications, ranging from
portable electronics to hybrid electric vehicles and
aerospace power electronics.},
