The relationship between the work function (ϕ), the frequency of light (ν), and the kinetic energy of the emitt electron (KE) is given by the Einstein equation:
KE = hν –
where h is Planck’s constant.
This equation is particularly useful when dealing with the photoelectric effect, where the wavelength of the incident light determines whether electrons will be eject from a material.
Would you like to explore any specific applications or implications of this equation?
work function hopg
The work function of highly orient pyrolytic graphite (HOPG) is typically around 4.8 eV. This value can vary slightly depending on the specific preparation and surface conditions of the HOPG sample.
