The edges of a single layer graphene (SLG) flake play important roles in determining the
electronic transport properties of graphene devices. Accurate determination of the phase …

Graphene field-effect transistors (GFETs) are considered promising devices as a result of
graphene's notably high mobility, flexibility, and ultrathin nature.[1, 2] Indeed, high mobility …

Raman spectroscopy is commonly used to determine the number of layers of few‐layer
