Researchers used an oxygen-free chemical vapor deposition (OF-CVD) method to develop high-quality graphene samples.
Researchers have developed a high-quality graphene sample by eliminating virtually all oxygen from the growth process. Graphene, which offers ultra-high electrical conductivity, has the potential to transform electronics, energy storage, sensors, biomedical devices, and more.
To move from lab explorations to real-world applications, researchers developed a method to synthesize large-area graphene about 15 years ago. The issue was oxygen. In prior publications, co-authors Richard Martel and Pierre Levesque from Montreal had shown that trace amounts of oxygen can slow the growth process and even etch the graphene away.
