Abstract: | A cyclotron resonance experiment on polarons in pure AgBr has been extended to the microwave field of 3 kV cm?1 by using a pulsed magnetron at 35 GHz at lattice temperatures of 4.2 and 17 K in magnetic fields up to 58 kOe. It was established that the ground state polaron mass is m1p(0)=(0.287±0.003)me. From microwave field dependences of the peak position and the width of resonance lines, it was established that the electron polaron follows the streaming motion repetitively emitting LO-phonons in the microwave field region above 80 V cm?1. Further, it was also suggested that, when streaming, the polaron has an enhanced effective mass of (0.353±0.006)me rather than the ground state mass m1p(0). |
