Comment on cond-mat/0409228 "Microwave photoresponse in the 2D electron system caused by intra-Landau level transitions"

Abstract

We provide an article-extract which points out that a microwave-induced modification in the resistance occurs at relatively "high" magnetic fields where the radiation is incapable of producing inter-Landau level excitations and, therefore, that the microwave radiation must be producing intra Landau level excitations as well.
