Deskripsi

Fabrication methods to pattern thin materials are a critical tool to build molecular scale devices. Here the authors report a selective etching method using XeF2 gas to pattern graphene based heterostructures with multiple active layers and achieve 1D contacts with low contact resistivity of 80 Ω·µm
