In this field configurations, the charge carriers are subjected to zero-dimensional confinement. Depending on the fields, we observe a complicated interplay of Wannier-Stark and Landau levels. The experimental spectra are found to be in good agreement with numerical results.enIII-V semiconductorIII-V HalbleitersuperlatticeÜbergitter621667530Influence of a strong magnetic field on the Wannier-Stark states of an electrically biased GaAs/Al(x)Ga(1-x)As superlatticeEinfluss eines starken magnetischen Feldes auf die Wannier-Stark-Zustände eines elektrisch vorgespannten GaAs/Al(x)Ga(1-x)As Übergittersjournal article
