Enhanced excitonic interactions in doped quantum wells in high magnetic fields
We report a strong enhancement and transformation of the Fermi edge singularity at high magnetic fields in a series of doped GaAs-Al33%Ga67%As quantum wells with width varying from 68 Angstrom to 150 Angstrom with carrier densities similar to4 (.) 10(11)cm(-2). We explain this behavior in terms of a...
