We study the magneto-optical properties of a Pöschl–Teller-like quantum well made of different materials such as GaAs, GaSb, InAs, and InSb. The energy difference becomes smaller with the wider well-width and becomes bigger with the deeper well-depth. The energy difference appears smallest in GaAs, followed by that in GaSb, while InSb shows the largest. The magneto-optical absorption coefficient (MOAC) shifts to the lower (higher) energy side when the well-width (well-depth and magnetic field) increases, but does not change the position with the change of temperature. The full-width at half-maximum (FWHM) increases with the increase of the well-depth, the temperature, and the magnetic field but decreases with the well-width. The phonon-emission process always happens stronger than the absorption one. The MOAC intensity in GaAs is the highest. The temperature-dependent-FWHM is supported by experimental results in GaAs quantum well.

我们研究了由GaAs，GaSb，InAs和InSb等不同材料制成的类似Pöschl–Teller量子阱的磁光特性。井宽越宽，能量差就越小；井深越深，能量差就越大。GaAs的能量差最小，其次为GaSb，而InSb的能量差最大。当阱宽度（阱深度和磁场）增加时，磁光吸收系数（MOAC）会移到能量的较低（较高）侧，但不会随温度的变化而改变位置。半最大全宽（FWHM）随井深，温度和磁场的增加而增加，但随井宽而减小。声子发射过程总是比吸收过程强。GaAs中的MOAC强度最高。
