Outline of Final Research Achievements

I researched the two themas; (1) we improved AFM (Atomic Force Microscope) lithography conditions, studied the chemical properties of oxidized area in graphene and fabricated graphene nano-structures by AFM lithography. (2) We fabricated the h-BN/Graphene/h-BN heterostructure and demonstrated mid-infrared photo detector with cyclotron resonance.
