Chaotic scattering in nano-electronic systems: from billiards to clusters
We review electron billiard experiments in which magnetoconductance fluctuations are used to investigate the role played by the billiard boundaries in determining electron interference processes. We present a unified picture of quantum interference across the ballistic and diffusive scattering regimes, in which the interference is shaped by an interplay between boundary scattering and chaotic scattering induced by the host material. We discuss the implications of this model for self-assembled nanoscale systems by considering bismuth nanoclusters.
