Debye velocity
WebDebye Length. The Debye length is a characteristic distance over which ions and electrons can be separated in a plasma (Chen et al., 1984) and is equal to the ratio of the electron thermal velocity divided by the plasma frequency. Webbe derived, the Debye velocity can be obtained by a para-bolic fit of the low-energy portion of the phonon density of states (Sturhahn and Jackson, 2007).
