Abstract

The melting properties of two-dimensional self-assembled hexadecanethiol monolayers were investigated. The heat capacity of the self-assembled monolayers (SAM) grown on polycrystalline gold surfaces was measured using nanocalorimetry technique with scanning rates of ∼30000 °C/s. When the alkanethiol was partially desorbed from the gold surface during thermal treatment, melting was found to occur over a broad temperature range with a melting temperature of about 70 °C. It was observed that SAMs have melting temperatures above 100 °C in their as-deposited state without desorption.
