Latest Patents: Maki Suemitsu's latest patents highlight her cutting-edge research. One notable patent describes a "stacked body including a graphene film and electronic device including graphene film." This invention includes a substrate made of silicon carbide that forms an angle of 20° or less with a silicon plane, along with a graphene film positioned on the substrate. The graphene film boasts an atomic arrangement that is oriented in relation to the silicon carbide substrate. A key aspect is that in the exposed surface of the graphene film, 50% or more of the area ratio exhibits a full width at half maximum of G' of 40 cm or less, according to Raman spectroscopy analysis. This innovation ensures high mobility in electronic devices that incorporate the graphene film.

Another of her patents involves a similar stacked body but with a focus on different parameters. This invention also uses silicon carbide as a substrate, forming an angle of 20° or less with a carbon plane. In this patent, the exposed surface of the graphene film is characterized by having ten or fewer regions per millimeter, with each region containing ten or more graphene layers and a circumcircle with a diameter of 5 μm to 100 μm. This feature further guarantees the stable high mobility necessary for effective electronic devices.
