WebAug 15, 2024 · hν is the photon's energy; Φ is the work function. Since E = hν = hc λ, the longer the wavelenght of the photon, the less energy it has. Therefore, the longest wavelength photon that can eject an electron will lead to almost zero kinetic energy for the ejected electron: 0 = hν − Φ Φ = hν = hc λ
WebThe physical principle for UPS characterization of the work function is straightforward, as is schematically summarized in Figure 1,for metals (a) and semiconductors (b), respectively. The photon energy, hν, is the sum of the kinetic energy (KE) and the binding energy (BE) of photoemitted electrons, on the basis of energy conservation. dfs sofas uk corner sofasWebThe physical principle for UPS characterization of the work function is straightforward, as is schematically summarized in Figure 1, for metals (a) and semiconductors (b), … chuty mejores rimasWebIn a rigorous treatment, the work function can be defined as the difference in energy between a neutral crystal and the same crystal but with one electron removed from the highest energy state. 4, 5 It is assumed in both cases that the crystal is in its ground state, that is, the lowest electronic states are completely filled.
