Obtained monolayers can then be transferred to any substrate, encapsulated, or created heterostructures using a transfer system. We work with a manual transfer system (HQ graphene) and a camera with imaging software to control the fabrication process. To store obtained samples, we use dry or vacuum desiccators preventing samples from degradation. To improve adhesion and remove surface residues, the substrate is cleaned using oxygen plasma treatment (Diener electronic).
