Restoring Ultra-Flat Bridgman-Fabricated Single-Crystal Cu(111) Wafers via Recrystallization Arrest Strategy for High-Quality Graphene Epitaxy
{{output}}
Single-crystal Cu(111) and its ultra-flat surface are crucial for the heteroepitaxy of high-quality, single-crystal graphene films with minimal folds and additional layers. Bridgman method coupled with cutting and chemical-mechanical polishing presents a strai... ...
