In pulsed high magnetic fields up to 40 T perpendicular to layers, we investigated photoluminescence (PL) from quasizero-dimensional carriers in modulation-doped GaAs/A1GaAs quantum wells for various electron densities at 77 K. We observed an oscillation of PL intensity due to magnetophonon resonanc
In the presence of a strong magnetic field (B) applied perpendicular to the interface of a two-dimensional electron system (2DES), the density of states for a 2D electron gas differs sharply from that at zero-magnetic field, which results in the total number of electrons in the structure differing f
