抄録

The formation and stability of a benzenedithiol monolayer on a Si substrate with a Au layer have been investigated to obtain a monolayer having high thermal stability as compared to that formed by use of a benzenethiol derivative. The monolayer was formed by immersing into an ethanol solution of 1,2-benzenedithiol (BDT). The work function of BDT-monolayer surface was measured for the investigation. The association constant for the adsorption of the molecules was estimated from the change of the work function. The subsequent annealing of the substrate with a BDT-monolayer at 500 K or lower did not lead to the change of the work function. Substrates with a BDT-monolayer were also examined using X-ray photoelectron spectroscopy (XPS). The work function and XPS spectra measured indicated that a BDT-monolayer formed on a Au surface is stable to annealing at temperatures up to about 473 K.
