Binding energy defined

Figure 3. Fe -H20 potential energy surface from Curtiss et al. (1987), and fit from parameterized Fe-0 potential function. Eb is the binding energy defined as E(FeH20 )-E(H20) (the energy of Fe is zero in the context of the ionic model).

When an impacting particle transfers energy to a near sinface carbon atom in an amount sufficient to overcome the lattice bond energy or surface binding energy, some carbon atoms may be displaced and move in a direction defined by the angle... 

According to equation 15, eigenvalues of the superoperator Hamiltonian matrix, H, are poles (electron binding energies) of the electron propagator. Several renormalized methods can be defined in terms of approximate H matrices. The... 

When put into an appropriate model [N0rskov et al., 2004], the binding energy correlations directly define a limit to t/o on the metals obeying the linear relations shown in Fig. 3.7. Since all intermediates are dependent on Eq, it is possible to plot the heights of all the steps AGi 4 as functions of Eq at zero potential. The step with the smallest free energy change wUl define I/ork (Fig. 3.8) ... 

Figure 3.8 Plots of the heights of the steps in Fig. 3.5 divided by the electron charge in order to get a potential. Via the relations in Fig. 3.7, these steps are all functions ofFo - On the vertical axis is the highest potential at which a step in the ORR is downhill in ftee energy, depicted as a function of the binding of O. The step that first becomes uphill in free energy defines (AEq)U. Steps 1 and 4 (lines labeled AGi and AG4, respectively) define the lower volcano and thereby t/oS (AFo)- Pt is the pure metal closest to the top.

The quantities averaged on the right here are the Boltzmann factor for the binding energy, as is usual for the PDT, but multiplied by the indicator function for the event that there are zero occupants of the defined inner shell. 

Here/(q) is the dipole oscillator strength distribution at q and e is the base of natural logarithm. The lowest excitation potential may be taken for qmin, whereas qmax = (E + EB)/2 with EB a defined mean electron binding energy (Mozumder and La Verne, 1984).
