在这封信中提出了基于石墨烯纳米管结的电子器件。非平衡绿色函数的计算表明，从具有不同边缘形状和宽度的单层石墨烯定制的纳米晶体管结可以充当金属/半导体结，并且可以实现量子点。凭借单层石墨烯图案化到原子精度的可能性，这些结构与先前报道的二维块状石墨烯或碳纳米管器件完全不同，预计将用作未来纳米电子学的构建模块。
Graphene nanoribbon junction based electronic devices are proposed in this letter. Nonequilibrium Green’s function calculations show that nanoribbon junctions tailored from single layer graphene with different edge shapes and widths can act as metal/semiconductor junctions and quantum dots can be implemented. In virtue of the possibilities of patterning monolayer graphene down to atomic precision, these structures, quite different from the previously reported two-dimensional bulk graphene or carbon nanotube devices, are expected to be used as the building blocks of the future nanoelectronics.
