We present here a novel approach to achieve the selective formation of different in-plane boronânitrogenâcarbon heterostructures on Pt(111) using a single molecular precursor, namely dimethylamine borane (DMAB). Through thermally activated decomposition and sequential bond activation it is possible to control intermolecular coupling and obtain alternatively a quasiâfreeâstanding continuous monolayer formed by complementary hexagonal boron nitride and graphene (G) large-size domains, or a pure or doped G monolayer, or hybridized layers with non-planar bonds. The selective bondâbond coupling is achieved by controlling the substrate temperature either during or after the deposition of DMAB. This allows on-surface synthesis of BâNâC materials with tunable composition.

Abstract
We present here a novel approach to achieve the selective formation of different in-plane boronânitrogenâcarbon heterostructures on Pt(111) using a single molecular precursor, namely dimethylamine borane (DMAB). Through thermally activated decomposition and sequential bond activation it is possible to control intermolecular coupling and obtain alternatively a quasiâfreeâstanding continuous monolayer formed by complementary hexagonal boron nitride and graphene (G) large-size domains, or a pure or doped G monolayer, or hybridized layers with non-planar bonds. The selective bondâbond coupling is achieved by controlling the substrate temperature either during or after the deposition of DMAB. This allows on-surface synthesis of BâNâC materials with tunable composition.File | Dimensione | Formato | |
