WebEffects of the ions are included using a simple pseudopotential theory, permitting the calculation of the variation of the work function from one crystal face to another. For simple metals (Li, Na, K, Rb, Cs, Al, Pb, Zn, and Mg), agreement with available experimental data is good (5-10%); for the noble metals, the computed work functions are 15-30% too low. Web4 mei 2024 · XPS and UPS measurements demonstrate unambiguously that there is no reaction between metallic lithium and nitrogen gas for the studied pressures. In our … Due to the complications described in the modelling section below, it is difficult to theoretically predict the work function with accuracy. Various trends have, however, been identified. The work function tends to be smaller for metals with an open lattice, and larger for metals in which the atoms are closely packed. … Meer weergeven In solid-state physics, the work function (sometimes spelt workfunction) is the minimum thermodynamic work (i.e., energy) needed to remove an electron from a solid to a point in the vacuum immediately outside the … Meer weergeven Thermionic emission In thermionic electron guns, the work function and temperature of the hot cathode are critical parameters in determining the amount of current that can be emitted.
