Carbon electrode for ferroelectric capacitor

A capacitor having a carbon-based electrode layer in contact with a ferroelectric insulator. The insulator may be a perovskite oxide. The low reactivity of the carbon-based electrode can improve the stability of the ferroelectric capacitor. The carbon-based electrode layer may be predominantly carbon and have a low resistivity. The carbon-based electrode layer may be the only layer of the electrode, or it may be a barrier layer between the insulator and another electrode layer. The two electrodes of the capacitor may include a carbon-based electrode layer, or the carbon-based electrode layer may be included in only one electrode. 具有与铁电绝缘体接触的碳基电极层的电容器。绝缘体可以是钙钛矿氧化物。碳基电极的低反应性可以提高铁电电容器的稳定性。碳基电极层可以主要是碳并且具有低电阻率。碳基电极层可以是电极的唯一层，或者它可以是绝缘体和另一电极层之间的阻挡层。电容器的两个电极可以包括碳基电极层，或者碳基电极层可以仅包括在一个电极中。
