High-resolution x-ray-diffraction spectra of Thue-Morse GaAs-AlAs heterostructures: Towards a novel description of disorder

Abstract

We present the first analysis of high-resolution x-ray-diffraction spectra of finite-size Thue-Morse GaAs-AlAs superlattice heterostructures, which show essential properties of singular continuous measures. The implications for future investigations of disordered systems are considered.
