Experimental Signatures of Wavefunction Scarring in Open Semiconductor Billiards

Semiconductor quantum dots provide an ideal experimental system for studying the transport signatures associated with wavefunction scarring in open billiards. In this report, we present the results of experimental and numerical studies that provide clear evidence for the role of scarred wavefunction states in transport through quantum dots. In contrast to scarring in closed billiards, an important feature of the dots we study is found t o be their open nature, which allows us to select the specific scars that are manifest in the transport behavior.
