SUMMARY
The discussion focuses on the calculation of the Bohr radius and velocity of excitons in semiconductors, specifically Gallium Arsenide (GaAs). Participants question the validity of using static permittivity in these calculations, particularly at high frequencies around ω=1015 Hz, where the mass of the electron and hole may influence the results. The consensus indicates that static permittivity can be applied under certain conditions despite the high-frequency measurements.
