ZEEMAN SPLITTING IN THE EXTREME QUANTUM LIMIT THROUGH CYCLOTRON-RESONANCE ON 2-DIMENSIONAL GAAS AT HIGH-PRESSURE

| description | Cyclotron resonance measurements on a GaAs heterojunction in the extreme quantum limit are presented. It has been reported recently that a new splitting appears for filling factors less than 1/6. We have applied hydrostatic pressure in order to investigate the dependence on electron g-factor, since a pressure of similar to 8 kbar halves the g-factor, yet changes the effective mass by only similar to 5%. The critical filling factor, defined as the point where the two split resonances have equal intensity, is found to be strongly reduced with pressure. A general relationship is presented for the dependence of the critical filling factor on the Zeeman splitting. |
