A concept for molecular electronics exploiting carbon nanotubes as both molecular device elements and molecular wires for reading and writing information was developed. Each device element is based on a suspended, crossed nanotube geometry that leads to bistable, electrostatically switchable ON/OFF states. The device elements are naturally addressable in large arrays by the carbon nanotube molecular wires making up the devices. These reversible, bistable device elements could be used to construct nonvolatile random access memory and logic function tables at an integration level approaching 10(12) elements per square centimeter and an element operation frequency in excess of 100 gigahertz. The viability of this concept is demonstrated by detailed calculations and by the experimental realization of a reversible, bistable nanotube-based bit.
开发了一种分子电子学概念，利用碳纳米管作为分子器件元件和用于读写信息的分子导线。每个器件元件基于悬浮的交叉纳米管几何结构，可导致双稳态、静电可切换的开/关状态。通过构成器件的碳纳米管分子导线，这些器件元件可在大型阵列中自然寻址。这些可逆的双稳态器件元件可用于构建非易失性随机存取存储器和逻辑功能表，集成度接近每平方厘米10(12)个元件，元件操作频率超过100吉赫兹。通过详细计算以及基于纳米管的可逆双稳态比特的实验实现，证明了这一概念的可行性。
