exotic quantum states double-layer graphene
2019/10/23
NSF-funded research by scientists at Brown and Columbia Universities has demonstrated the existence of previously unknown states of matter that arise in double-layer stacks of graphene, a two-dimensio...
Uinversity of Illinois at Chicago researchers have discovered a way to create a highly sensitive chemical sensor based on the crystalline flaws in graphene sheets. The imperfections have unique electr...
Ballistic transport in graphene suggests new type of electronic device（图）
