Alfonso Sanchez-Soares, Thomas Kelly, Giorgos Fagas, James C. Greer, Edward Chen

摘要:

我们提出了量子模拟的碳纳米管场效应晶体管(CNT-FET)的顶栅架构的基础上,并与15 nm的沟道长度的设备上的电气特性进行比较。一个非平衡格林函数(NEGF)的量子输运方法加上$\vec{k} \cdot \vec{p}$描述的电子结构被证明达到良好的协议与报道的实验数据。影响通道的静电控制的因素进行了研究,并揭示了详细的建模的静电和CNT的电子能带结构需要实现定量与实验一致。

英文摘要:

We present quantum simulations of carbon nanotube field-effect transistors (CNT-FETs) based on top-gated architectures and compare to electrical characterization on devices with 15 nm channel lengths. A non-equilibrium Green's function (NEGF) quantum transport method coupled with a $\vec{k} \cdot \vec{p}$ description of the electronic structure is demonstrated to achieve excellent agreement with the reported experimental data. Factors influencing the electrostatic control of the channel are investigated and reveal that detailed modeling of the electrostatics and the electronic band structure of the CNT is required to achieve quantitative agreement with experiment.
