It is shown that semiconductors, for particular scattering mechanisms, may have a strong peak in the conductivity s̀′(ω), if the ratio of the dc‐scattering frequency and the plasma resonance frequency is larger than one. This peak immediately leads to a velocity overshoot for cold electrons, when applying an electric field pulse.
