abstract
The adsorbed state of diethylzinc on the (0001) and (0001̄) surfaces of zinc oxide was examined by TPD, XPS, and UPS. These techniques demonstrated that diethylzinc was adsorbed intact, with little detectable difference in its interaction with the two polar surfaces. XPS and UPS provided evidence for energy levels of diethylzinc which were outside the range observed for other carbon-containing adsorbates on zinc oxide, suggesting that these techniques are suitable for the detection of surface alkyls. 1989.
