The modification of crystalline silicon surfaces with covalently-attached alkyl chains was spectroscopically studied using a chlorination/alkylation method. Ellipsometric measurements indicated that the thickness of the alkyl overlayer varied monotonically with the length of the alkyl group used in the reactant. Contact angle and infrared measurements indicated that the packing of alkyl groups in the monolayers was less dense than that found in alkylthiol monolayers of gold.
