Free-Electron Screening Mechanism of the Shallow Impurity Breakdown in n-GaAs: Evidences from the Photoelectric Zeeman and Cyclotron Resonance Spectroscopies

Figure 18

Low temperature () structures of the CR lines, measured for the sample 6 at different electric fields corresponding to curves 1, 2, and 3, and aligned parallel to the magnetic field , for (a) and (b) . The broad line in 1b is due to the transition indicated by arrow in Figure 14, the intensity of which decreases with increasing the prebreakdown electric field.
