|Title:||Electron Interactions with c-C4F8|
|Published:||January 01, 2001|
|Abstract:||The limited electron collision cross-section and transport-coefficient data for the plasma processing gas perfluorocyclobutane (c-C4F8) are synthesized, assessed, and discussed. These include cross sections for total electron scattering, differential elastic electron scattering, partial and total ionization, dissociation into neutral fragments, and electron attachment. There is only one measurement of the electron transport, ionization, and attachment coefficients. The available data on both the electron collision cross sections and the electron transport coefficients need further scrutiny. Also, measurements are needed of the momentum transfer and elastic integral cross sections, and of the cross sections for other significant low-energy electron collision processes such vibrational and electronic excitation. In addition, electron transport data over a wider range of values of the density-reduced electric field are needed. The present assessment of data on electron affinity, attachment, and scattering suggests the existence of negative ion states at about - 0.6 eV, 4.9 eV, 6.9 eV, 9.0 eV, and 10.5 eV.|
