Photoluminescence Detected Doublet Structure in the Integer and Fractional Quantum Hall Regime

Journal Article · · Solid State Communications
OSTI ID:7063

We present here the results of polarized magneto-photoluminescence measurements on a high mobility single-heterojunction. The presence of a doublet structure over a large magnetic field range (2>v>l/6) is interpreted as possible evidence for the existence of a magneto-roton minima of the charged density waves. This is understood as an indication of strong electronic correlation even in the case of the IQHE limit.
