Changes in work function of the TiC (001) surface have been measured against O2 and H2O exposure by using photoelectron spectroscopy. The sticking rates are about 1/100 of those for elemental Ti-metal substrate. In the case of oxygen exposure, the work function increases monotonically from 3.8 to 4.2 eV, whereas for H2O a maximum value of work function occurs at an exposure of ∼300L, and its value finally reaches 4.5 eV.
