Latest Patents

Qiucheng Li holds a patent for "Self-assembled borophene/graphene nanoribbon mixed-dimensional heterostructures and method of synthesizing same." This invention relates to a method of synthesizing a self-assembled mixed-dimensional heterostructure that includes 2D metallic borophene and 1D semiconducting armchair-oriented graphene nanoribbons (aGNRs). The method involves depositing boron on a substrate to grow borophene in an ultrahigh vacuum (UHV) chamber. It also includes sequentially depositing 4,4″-dibromo-p-terphenyl on the borophene substrate at room temperature to form a composite structure. The process controls multi-step on-surface coupling reactions to self-assemble a borophene/graphene nanoribbon mixed-dimensional heterostructure. The resulting lateral heterointerfaces are structurally and electronically abrupt, demonstrating atomically well-defined metal-semiconductor heterojunctions.
