The search of new electronic materials for high-temperature applications has been a significant challenge in recent years. In automotive industries, for example, cutting-edge technology requires electronic components operable at high temperatures (> 200 °C). The absence of suitable capacitors is one of the major barriers to meet this goal. Here we provide a solution to these issues by using an atomically-thin perovskite nanosheet (Ca2Nb3O10), a twodimensional material derived from the exfoliation of a layered compound. Through in-situ characterizations, we found a robust thermal stability of Ca2Nb3O10) nanosheet even in a monolayer form (~ 2 nm). Furthermore, layer-bylayer assembled nanocapacitors retained both size-free high-ϵr characteristic and high insulation resistance at high temperatures up to 250 °C. The simultaneous improvement of ϵr and thermal stability in high-k nanodielectrics is of critical technological importance for the use of high-temperature capacitors.
