Conventional and localized photoluminescence (PL) are investigated in an n-type asymmetrically doped InGaAs/InP quantum well (QW), using focused laser-beam excitation. We observed a novel red shift in the PL spectra and also the presence of an additional transition, under high optical excitation int

We present data which shows for the ΓΏrst time that an exchange-driven bilayer-to-monolayer transition occurs in an externally biased double quantum well system at B = 0 as the total carrier density is increased. This transition is due to the negative compressibility of the low density carrier system
