Summary, in English

We study low temperature magnetoconductance fluctuations in arrays of electron billiards in an effort to quantitatively measure hybridization between array elements. In contrast to previous research in the 'open' regime, which is mostly limited to the canonical AlxGa1-xAs/GaAs heterostructure, our devices are etched into the Ga0.25In0.75As/InP heterostructure. To chart hybridization (i.e. the extent of the coherent electron wavefunction) in the arrays, we use a Fourier analysis to examine the frequency content of the universal conductance fluctuations in one and two element arrays. This analysis reveals strong evidence of wavefunction hybridization over all measured coupling strengths between the array elements. (c) 2009 Elsevier B.V. All rights reserved.
