Electrochemical Delamination and Chemical Etching of Chemical Vapor Deposition Graphene: Contrasting Properties

摘要: Recent advancements in chemical vapor deposition techniques for the growth of graphene have enabled access to large-area and high-quality film various applications. The key step determining quality final films is transfer process desired substrates, with goal minimizing amount structural modification film. Multiple methods exist this process, each method varying extent which altered. Four fundamentally different methods, including etching electrochemical delaminating, were employed obtain from grown on Ni foil resulting characterized using scanning electron microscopy, Raman spectroscopy, X-ray photoelectron cyclic voltammetry. These showed noticeable differences their material properties terms defects elemental purities, a dramatic i...
