Multiterminal electron transport in a quantum dot lattice — •Christian Morfonios1, Daniel Buchholz2, and Peter Schmelcher1 — 1Zentrum für Optische Quantentechnologien, Universität Hamburg, Luruper Chaussee 149, 22761 Hamburg, Germany — 2Physikalisch-Chemisches Institut, Universität Heidelberg, Im Neuenheimer Feld 229, D-69120 Heidelberg, Germany
The multiterminal transport of electrons through a lattice of coupled quantum dots is studied in terms of the array topology and geometry, the internal features of its nodes, and an applied magnetic flux. The scattering properties of individual dots are addressed through separation of interfering lead-coupled states, boundary guiding and magnetic deflection. By assembling the dots into a lattice of variable spacing, connectivity and terminal positioning, the possibility of mode-resolved control of scattering between input and output lead states is investigated.
