On-surface synthesis of two-dimensional molecular film and transition metal adsorption

Abstract

We examined to form a two-dimensional molecular lattice film on noble metal surfaces in ultrahigh vacuum using precursol molcecules via Ullmann coupling. We used Cu(111) and Au(001) substrates. Sample surface morphology was measured by means of scanning tunneling microscope and low energy electron diffraction. Sample electronic structures were investigated by scanning tunneling spectroscopy and ultraviolet photoelectron spectroscopy. We will report in detail.
