WebWork function measurement techniques: The work function of a material can be measured with PES and Kelvin probe (KP). While PES allows the measurement of the absolute work function, KP only gives the ... The best bet, in our opinion is to use highly oriented pyrolytic graphite (HOPG), which after cleavage has a work function of about … WebA work function of 2.1 eV is achieved in the first 10 s of plasma, while further plasma exposure leads to the removal of Cs from the surface and to the change of the work function: a value of ...

The retarding potential method has been used to measure the work function changes due to Cs adsorption on the graphite (0001) surface. The work function decreases sharply and linearly with increasing Cs coverage up to a coverage θ = 1 × 10 14 atoms cm 2 after which there is no significant change. The work function minimum is … dice ゴーグル showdown
