Special Issue Information
Dear Colleagues,
We are pleased to invite you to contribute to this Special Issue on High-Mobility Graphene Structures. Graphene’s exceptional electronic properties, particularly its potential for ultra-high carrier mobility, have positioned it at the forefront of research on two-dimensional materials. Achieving high mobility is essential for exploring quantum effects and deepening our understanding of fundamental physics in graphene and related materials.
Recent advancements in fabrication techniques—such as polymer-free transfer methods, substrate cleaning by annealing, and the use of special substrates like hexagonal boron nitride (hBN) and tungsten diselenide (WSe2)—have significantly improved the mobility of graphene samples. These developments have enabled the observation of phenomena such as long mean free paths for charge carriers and spin transport, enhanced Coulomb drag in double-layer structures, and exciton condensation effects.
This Special Issue aims to present the current state of research in high-mobility graphene structures, highlighting substrate selection and innovative fabrication methods that contribute to high mobility. By focusing on these advancements, the Issue aligns with the journal's scope of exploring cutting-edge materials science and nanotechnology. The collection of articles will provide valuable insights into how high mobility facilitates the discovery of new physical properties and phenomena in graphene, thus advancing knowledge in this exciting field. Research areas may include (but are not limited to) the following:
- Advanced fabrication methods for high-mobility graphene, including polymer-free transfer techniques;
- Record mobility values achieved in graphene and related measurement methodologies;
- Substrate preparation methods such as cleaning by annealing to enhance mobility;
- Special substrates (e.g., hBN, WSe₂, layered dielectrics) that support and enhance graphene mobility;
- Impact of high mobility on the observation of new quantum phenomena, including exciton condensation;
- Spin transport and charge carrier dynamics with long mean free paths in high-mobility graphene;
- Double-layer graphene structures exhibiting phenomena related to Coulomb drag;
- Studies on carrier transport, quantum effects, and the influence of impurities, defects, and environmental factors on graphene mobility.
In this Special Issue, original research articles and reviews are welcome. We look forward to receiving your contributions.
