Abstract

The dispersion of the composite-fermion cyclotron-resonance mode is measured with an optical detection scheme under the combined excitation of microwave radiation and a surface acoustic wave from an interdigital transducer. The slowly traveling surface wave defines the transferred wave vector. Momenta up to 108 m-1 are accessible. The cyclotron-resonance mode exhibits strong negative dispersion, ...
