• molecules are influenced by the nature of the substrate, which has been attributed to different substrate–molecule interactions [9]. With the application of 2D materials, such as graphene in device configurations, it is important to understand the orientation of MPc molecules on these atomically thin

• materials [10][11]. A single-layer of graphene can serve as a transparent conducting electrode and function as donor or acceptor when combined with suitable organic counterparts [12][13]. However, graphene itself is supported on a rigid substrate for device integration and, hence, it is important to

Moreover, the proposed configuration allows the implementation of a FrFT with a tunable order in atomically thin materials in which the charge carriers obey either the Schrödinger equation (as

If measurable, a tunable FrFT could be used to gather information on the quantum wave function of charge carriers. In atomically thin materials [23][24], as well as in graphene [25], only mappings of
