高移動度グラフェンデバイスがhBN単結晶に依存する理由

Graphene is widely regarded as one of the most remarkable materials ever discovered. Its exceptional electrical conductivity, mechanical strength, and atomic thickness have opened new possibilities in nanoelectronics, sensing, and quantum technologies. However, one of the most important discoveries in graphene research is that its performance is not solely determined by graphene itself—but critically depends on the underlying substrate material. Among all known substrate materials, hexagonal boron nitride (hBN) single crystal has proven to be the most effective platform for achieving high-mobility graphene devices. This article explains why hBN single crystals are essential for unlocking graphene’s true electronic potential. The Challenge: Graphene Is Extremely Sensitive to Its Environment Although graphene […]
