Abstract:
1. A method comprising the steps of: a) reacting a Si surface with a quantity of functionalizing agent to form a functionalized Si surface, wherein the functionalizing agent comprises an oligo(phenylene ethynylene) comprising an aniline end and a diazonium end, and wherein the reacting is carried out in the presence of HF so as to provide for a continual hydride passivation of the Si surface; b) dispersing a quantity of CNTs in a solvent to form dispersed CNTs; and c) reacting the functionalized Si surface with the dispersed CNTs to form a CNT-Si composite structure comprising CNTs molecularly grafted to the Si surface, wherein during the reacting step, the aniline end of the oligo(phenylene ethynylene) is converted to a diazonium species by treatment with a converting species selected from the group consisting of inorganic nitrites, organic nitrites, alkyl nitrites, sodium nitrites, potassium nitrites, NOBF
