"with certain acetylene concentration, more hydrogen near surface enables more diamond to form, even at lower, soot suppressing temperature... some applications require nitrogen-vacancy centers: quantum diamonds, potentially qubits... plasma-surface interaction: more reliable/ less damaging adding single layer hydrogen atoms... 2 new methods: cold plasma termination, forming gas annealing... semiconductors, quantum computing, secure communications, optics, biomolecular sensing (temperature, magnetic fields)"
