利用倾斜磁场中的低温输运实验研究了抛物量子阱。属于不同子带的占据朗道能级的共振反交叉直接表现在磁电阻中。这允许直接评估系统的单粒子能谱
A parabolic quantum well is investigated by low-temperature transport experiments in tilted magnetic fields. The resonant anticrossing of occupied Landau levels belonging to different subbands is manifested directly in the magnetoresistance. This allows a direct evaluation of the single-particle energy spectrum of the system
