"terraced graphene substrate—essentially an atomic-scale staircase—and heated it to around 1600 degrees Celsius before spraying on individual boron and active nitrogen atoms. The result far exceeded the team's expectations, forming neatly ordered seams of hBN on the graphene's terraced edges, which expanded into wide ribbons of material"
