Is hydrogen plasma to remove oxide from graphene oxide wafers a feasible, sustainable alternative to photoresist? Re: graphene oxide https://news.ycombinator.com/item?id=43955611 https://news.ycombinator.com/item?id=43955611 : > What types of graphene and other forms of carbon do not conduct electricity, are biodegradable , and would be usable as a graphene PCB for semiconductors and superconductors? > Graphene Oxide (low cost of production), Graphane (hydrogen; high cost of production), Diamond (lowering cost of production, also useful for NV QC nitrogen-vacancy quantum computing; probably in part due to the resistivity of the molecular lattice), > How could graphene oxide PCBs be made fire-proof? Salt; like insulation batting. Maybe even processed brine?
