Abstract

Transverse magnetic focusing in arrays of abutted square cavities and commensurability oscillations in antidot superlattices were investigated around half Landau-level filling in a two-dimensional electron gas. Both experiments support the validity of the composite fermion model and confirm that composite fermions appear to obey quasi-classical dynamics. Nevertheless, compared to electrons, the ...
