Space Homogeneous Solutions of the Linear Semiconductor Boltzmann Equation

Abstract: The linear Boltzmann equation describing electron flow in a semiconductor is considered. The Cauchy problem for space-independent solutions is investigated, and without requiring a bounded collision frequency the existence of integrable solutions is established. Mass conservation, an H-theorem, and moment estimates also are obtained, assuming weak conditions. Finally, the uniqueness of the solution is demonstrated under a suitable hypothesis on the collision frequency.

“…Thus, we merely restrict ourselves here to a few remarks on the critical case in the whole space. This equation is formally similar to the linear Boltzmann equation of gas; see for instance [3,7,[16][17][18]. Actually, the difference between them resides in the peculiarity of scattering events.…”

“…In radiative transfer, the phase function integrated over outgoing directions is dominated by the extinction coefficient [7,29]. In cell growth modeling [28], electron transport in weakly ionized gases [15], rarefied gas dynamics [6], and modeling of electron-phonon interaction in semiconductors [18,19], the integrated (nonnegative) collision kernel is exactly equal to the collision frequency. In fact, Eq.…”

“…The situation as described in the preceding paragraph occurs in various applications, such as electron transport in weakly ionized gases [15], cell growth modeling [20], and modeling of electron-phonon interactions in semiconductors [19]. In these papers, sufficient conditions for having the isometry condition (3.15) are derived and the possibility of not having (3.15) is discussed, though without providing explicit models in which the isometry relation (3.15) is not satisfied.…”
