Good time.

"The Surface Science of Metal Oxides" By Victor E. Henrich, P. A. Cox (Table 1.1, p. 9)

Also, you can extract some information from: Materials 2010, 3, 4892-4914; doi:10.3390/ma3114892

Also, as showed early, PWF can be modified.

Hi,

Many thanks. All your references are usefull and have been downloaded.

Many thanks Artur. Even, if i have already asked about ZnO work function data, those corresponding to CdO are welcome too. Unfortunately, as i have said to Nrisimhamurty Madugula, a quick reading of this thesis has not shown any work function data for both metal oxides CdO and ZnO.
