Organic modification of semiconductors or functionalization is a fast
growing field due to the need to create devices, exploiting the properties
of organic and inorganic materials, capable of molecular recognition and
chemical or biological sensing.
Different methods in wet or dry environment have been developed some of them
photo assisted.
Silicon substrates have been widely used for these studies [1] and only
recently Diamond substrates have been considered.[2]
In this talk I will present electron induced functionalization method of
Diamond substrates which consists in depositing few layers of organic
compounds on non-reactive hydrogenated surface and irradiating this film
with low energy electrons.
Results on hydrogenated diamond/CH3CN system will shown.
