This paper reports a new method of measuring the work function of meterials. The method is based on accurate measuring of energy distribution of secondary electrons and contact potential difference of meterials. We call it the method of secondary electron emission-contact potential difference (SEE-CPD method). The work function of pure metals of Ni, Al, Au and Mo were measured by this method. The results are well consistent with that obtained by using photo-electron and Kelvin's method. The fundamentals and applications of the SEE-CPD method are proved to be correct and reliable.
