Photoelectron spectra of benzo[a]pyrene and benzo[e]pyrene have been assigned on the basis ofab initioelectron propagator theory. Electron correlation effects are included in the partial third order approximation and agreement with experimental peaks is very close. To each ionization energy, there cor...

The total ionization cross sections of He, N2, H2 and O2 due to electron impact have been calculated by integrating the expressions given by Khare for the ionization cross sections per unit energy range. The results are in satisfactory agreement with the experimental data. Comparison has also bee...

Similar ideas about the processes of tunnel and multiphoton ionization in dielectrics, which govern the transitions of electrons from valence to a conduction band, were also generalized in [12]. In this case, when writing Expressions (2–5), the width of the energy bandgap serves as an analogu...
The ionization energy of N2 (IE = 15.6 eV) also exceeds that of most organic molecules, making N2 ideal for the analysis of a wide range of compounds, as is often required for NTS. In some cases, it may be desirable to select a gas with an ionization energy that lies above that of...

1.2 Ionization Energy The ionization energy of a dopant determines the fraction of dopants that contributes free carriers at a given temperature. A high ionization energy limits the doping efficiency: for instance, the ionization energy of Mg in GaN (around 200 meV) is so large that at room te...
