Abstract

We have observed angular dependent cyclotron resonance (CR) of two-dimensional electrons confined in GaAs/Al-GaAs multi quantum wells in ultra high magnetic fields up to 150 T generated by the single-turn coil technique. We changed the tilt angle between the magnetic fields and the direction normal to the two-dimensional plane. Three samples with different well widths and aluminum concentrations of barrier layers were measured. We found four different types of angular dependence of CR and interpreted these comprehensively on the basis of the relations among barrier height energy Vb, subband spacing energy E10 and cyclotron energy ℏωc.
