N-Alkanes confined in Nanoporous Silicon: An Infrared Spectroscopy and X-ray Diffraction Study — •Anke Henschel, René Berwanger, Klaus Knorr, and Patrick Huber — Technische Physik, Universität des Saarlandes, 66123 Saarbrücken
The conformation and arrangement of linear hydrocarbons (C16H34-C21H44) confined in tubular pores of porous silicon (mean pore diameter 10nm) is investigated by combined infrared spectroscopy and x-ray diffraction measurements. We find distinct changes in the vibration characteristics, in the structure factor as well as the phase transition temperatures of confined n-alkanes as compared to the bulk phases.
