What Challenges Exist in Graphene-Based Interconnects?
Despite its remarkable properties, there are several challenges in implementing graphene-based interconnects:
1. Contact Resistance: High contact resistance at the interfaces between graphene and metal contacts can limit performance. 2. Integration: Integrating graphene with existing semiconductor technologies involves complex fabrication processes. 3. Defects and Grain Boundaries: Imperfections in graphene sheets can significantly affect their electrical and mechanical properties. 4. Cost: The production of high-quality graphene at a low cost remains a significant challenge.
