Deposition of organic molecules with vinylic group on hydrogenated Si(100)

Depositing a monolayer of molecules on top of the most important semiconductor material, i.e. silicon, in order to obtain hybrid heterostructures is the main purpose of this work. Aromatic and heteroaromatic molecules with a vinylic group reacting with hydrogenated silicon atoms on a Si(100) surface by a radical reaction promoted by heat are studied. The molecular grafting occurs through the vinylic function while preserving the original molecular structure and molecular properties. After depositing the organic materials samples are analysed with atomic force microscopy (AFM) in order to verify the coverage level, film thickness and topographic features.
