基于碳纳米管（CNT）的集成电路（IC）包括基本的逻辑和算术电路被证明在低至0.4V的电源电压下工作，该电源电压比传统硅IC中使用的电源电压低得多。CNT电路的电源电压的下限由引起阈值电压波动的工艺引起的劣化的噪声容限确定。降低电源电压可以显著降低碳纳米管集成电路的功耗，这对进一步开发更高集成度的纳米电子集成电路至关重要。
Carbon nanotube (CNT) based integrated circuits (ICs) including basic logic and arithmetic circuits were demonstrated working under a supply voltage low as 0.4 V, which is much lower than that used in conventional silicon ICs. The low limit of supply voltage of the CNT circuits is determined by the degraded noise margin originated from the process inducing threshold voltage fluctuation. The power dissipation of CNT ICs can be remarkably reduced by scaling down the supply voltage, and it is of crucial importance for the further developments of nanoelectronics ICs with higher integration density.
