Abstract
The electron beam chopping technique has enabled the true secondary el ectrons to be extracted from the overcoming background of thermionic a nd stray electrons, leading to a precise assessment of the work functi on change from the measurement of the onset of the spectrum. This tech nique was applied to the O/W(100) system at similar to 1100 K. The wor k function has revealed a stepwise change against the oxygen exposure time.
