ABSTRACT
As we have learnt before, SWCNTs exist in a variety of flavours, or chiralities, each with their unique electronic properties. This is both an advantage and a disadvantage in the application of SWCNTs in electronics. On one hand, it allows for various different electronic components such as transistors and interconnects to be fabricated from different SWCNT flavours, making an “all-carbon” electronic circuit possible. On the other hand, chirality or even electronic-type (metallic or semiconducting) specific synthesis of SWCNTs has proven elusive. When SWCNTs are grown with mixed chiralities, it poses a major challenge in placing specific kinds of SWCNTs at specific locations in a circuit on wafer scale to realize the aforementioned all-carbon electronics.
