Abstract
We report the observation of a strong anomaly in the magnetic-field dispersion of negatively charged excitons in dilute two-dimensional electron systems. The anomaly exists in an intermediate density range around 1×1011 cm–2, and at temperatures T<1 K, only. The strength of the anomaly at T = 0.1 K is about 2.5 meV, and the most striking feature is that it can be completely destroyed by a ...
