Abstract

sed on variable temperature ultrahigh vacuum scanning tunneling microscopy data, we propose a two dimensional phase diagram of monolayerdecanethiol on Au(111). Four triple point temperatures were determined: T1 at 27 C, T2 at 33 C, T3 at 35 C, and T4 at 56 C. The T1 triple point defines the lowest temperature melting point; the T4 triple point defines the temperature above which striped phases are metastable. These data provide a fundamental framework to understand and control meso-scalemonolayer structure; moreover, they provide fundamental insight into two dimensional phase behavior of molecules with many degrees-of-freedom.
