Graphene is said to be the most conductive material in the universe ( at room temperature I assume else a superconductor would be more conductive ) and has several properties that make it suitable for nano electronics especially in microchips. But much emphasis is placed on the fact that it doesn't have a band-gap and that makes it hard to use it as a semiconductor in a transistor.
But I really fail to see why such emphasis is placed on this fact because I fail to see why this is a problem because, and this is my burning question here, why not just use the graphene for wherever you need conductors in a microchip ( which will be in the transistor leads and nano-wires ) but simply use a none-graphene semiconductor ( perhaps doped silicene? ) wherever you need a semiconductor ( which will be in the transistors where the leads meet ) ? I mean, is there something I am missing here? I mean, is there a reason I am not aware of why doing that would be problematic?
Also, graphene is made of pure carbon and silicene is like graphene in structure but made of pure silicon. But what is the graphene analogy for carborundum ( Silicon carbide ( SiC ) ) ? You could have a 2D graphene structure but where each atom of carbon is bonded to 3 silicon atoms and each silicon atom is bonded to 3 carbon atoms. What would such a material be called? ( I tried googling various wildly guessed names such as “carborundumene” and “siligraphene” but had no luck ) and what would be its electrical properties ( if known ) and has this material been researched as a possible material for electronics? ( any web links? )
