The electronics industry might look very different today were it not for the dramatic drop in cost of high-quality single-crystalline silicon wafers over the past five decades. So what would happen if the cost of single-crystalline graphene took a similarly significant plunge? Results reported in ACS Nano may bring this closer to reality, as they show that single-crystalline graphene can grow in a fraction of the usual time and using much cheaper polycrystalline substrates than usually needed.
