Title: Volatilization Behavior of Supported Au Nanoparticle Arrays under H2 at High Temperature

Abstract

In this work, the fabrication and experimental study of model Au nanoparticle arrays (nanodots) was used to allow a direct comparison of reactive evaporation at elevated temperatures and nonambient H2-containing gas atmospheres with theoretical models. Strong temperature and H2-concentration dependencies were confirmed as expected, and the observed dependence in particle diameter with time was effectively described using a reactive evaporation and gas phase diffusion based quantitative model.
