Webof the work function of tungsten, the work function of the other surface may be obtained. It will be clear, however, that unless the two curves are parallel, at least within the limits of experimental error, it will not be possible to assign a definite value to the contact-potential difference. This requirement has an important bearing http://rsl.eng.usf.edu/Documents/Tutorials/TutorialsWorkFunction.pdf
