Interface Phase Engineering of Monolayer Sb₂O₃ on Au(111)

Abstract

By subtle control over the deposition flux and growth temperature of inorganic dielectric molecular Sb2O3, two kinetic phases and a thermodynamically stabilized phase were successfully obtained on Au(111). Phase transition processes and selective growth of molecular self-assembly were monitored by STM, backed up by DFT calculations. Furthermore, theoretical calculations elucidate the impact of molecular arrangement on the modulation of dielectric properties.
