You need an insulator to separate those carbon nanostructures. In comes boron nitride, which will make nanotubes like carbon, and is an insulator: en.wikipedia.org/wiki/Boron_nitride_nanosheet"BN nanosheets are used as substrates for graphene-based devices" It can be hybridized with graphene as a borocarbonitride sheet. Also, borophene exists (2-D boron sheets). |

Start with a diamond substrate, dope it, form graphite structures on its surface, etch it, realize you have no reasonable way to make insulators and stop until that is figured out?

Graphene transistors, carbon conductors and boron nitride insulators... would make for extremely durable electronics.

Yeah, basically he's saying that you could make it so that the transistors were structurally integrated into the chip/chipset, so that you don't need as much material to keep it from breaking. Another advantage of carbon allotrope transistors (with possible added boron nitride) is that they are likely to keep functioning even at relatively high temperatures, meaning that you don't need as much cooling equipment, which reduces the overall weight of the support structures, due to not needing to keep as much cooling equipment stationary relative to what it's cooling and you don't need as large a power supply to run both the cooling and the computer system. |

Isn't the amount of cooling for transistors need a bit insignificant compared to other things on a spaceship? Hull (Solar light), engines, weapons, life support etc. |
