Chang-Hua Liu, Chung-Chiang Wu, Zhaohui Zhong

摘要:

我们展示了一个完全可调的二极管结构,利用完全悬浮的单壁碳纳米管(SWNT)。通过控制栅极电压,二极管在正向偏压下的导通电压可以连续调节到4.3 V,这是纳米管带隙能量的约6倍。此外,通过利用栅极电压调谐带间隧穿电流,可以将相同的器件设计配置成反向二极管。首次研制出非线性超过理想二极管的纳米管反向二极管。这些结果表明,可调谐纳米管二极管可以是一个独特的构建块,用于开发下一代可编程纳米电子逻辑和集成电路。

英文摘要:

We demonstrate a fully tunable diode structure utilizing a fully suspended single-walled carbon nanotube (SWNT). The diode's turn-on voltage under forward bias can be continuously tuned up to 4.3 V by controlling gate voltages, which is ~6 times the nanotube bandgap energy. Furthermore, the same device design can be configured into a backward diode by tuning the band-to-band tunneling current with gate voltages. A nanotube backward diode is demonstrated for the first time with nonlinearity exceeding the ideal diode. These results suggest that a tunable nanotube diode can be a unique building block for developing next generation programmable nanoelectronic logic and integrated circuits.
