Abstract

Introducing spatial autocorrelation analysis of nanophotoluminescence images of atomically rough single GaAs quantum wells, we show that the bright spots in the images are not randomly distributed but rather tend to "repel each other" along certain directions. Simple computer simulations on the anisotropic transport of excitons in the disorder potential and on the resulting images can reproduce this surprising behavior.
