In this paper, surface of gold impregnated with thiophene was studied by the Time of Flight secondary Ion Mass Spectrometry ( TOF-SIMS). Some characterizations of gold-sulfur cluster ions of structures and chemical qualities are obtained.
Using the Time of Flight Secondary Ion Mass Spectrometry (TOF-SIMS), the interface interaction between ethyl mercaptan and gold is observed. A series of gold-sulfur cluster ions are shown on the mass spectrum, which demonstrate the Self-Assembled Monolayers (SAMs) between mercaptan and gold
