The effect of pressure - by definition a 3-dimensional concept - on
2-dimensional systems brings a number of fundamental questions, which
have been partly answered through newly engineered samples and
experimental setups. In this review of the high-pressure Raman studies
of graphene, we will in particular underline the importance of the
presence of a supporting substrate and its role for the production of
biaxial strain conditions in high pressure experiments. Raman shifts
observed during these experiments may be related to the strain induced
by the substrate rather than by the applied pressure, graphene stress,
and hydrostatic pressure not being straightforwardly equivalent in this
case of a composite 2D-on-3D material. We will also consider the effects
of the nature of the substrate surface, the nature of the pressure
transmitting media, as well as the effect of the number of layers on the
high-pressure response of the 2D-system, by using the phonon behavior as
strain probe as pressure is applied. The effects of adhesion and of
strain transfer from the substrate to the 2D-system will be at the heart
of our discussion. Copyright (c) 2017 John Wiley & Sons, Ltd.
