Eigenvalue Solution to Steady-State Boltzmann Equation
We show that a basis of orthogonal Hermite polynomials can be used in the recently developed eigenvalue method  for solving the Boltzmann equation. A small number of basis functions is sufficient to well represent the distribution function. Calculated velocity-field characteristics at electric field strengths less than 7 kV/cm agree well with experimentally measured values in GaAs.
