摘要:

我们报道了在六方氮化硼(hBN)薄片上制备第一个碳纳米管(CNT)量子点的细节和低温特性。我们表明,碳纳米管可以生长在hBN通过标准的化学气相沉积和标准的扫描电子显微镜成像和光刻可以采用优化的参数时,制造纳米电子结构。这种概念验证为hBN上更复杂的器件铺平了道路,具有更可预测和可再现的特性和电子稳定性。

英文摘要:

We report the fabrication details and low-temperature characteristics of the first carbon nanotube (CNT) quantum dots on flakes of hexagonal boron nitride (hBN) as substrate. We demonstrate that CNTs can be grown on hBN by standard chemical vapor deposition and that standard scanning electron microscopy imaging and lithography can be employed to fabricate nanoelectronic structures when using optimized parameters. This proof of concept paves the way to more complex devices on hBN, with more predictable and reproducible characteristics and electronic stability.
