Title: Conductance anomalies in quantum point contacts
Authors: Frucci, Giulia
Keywords: electronic transport , quantum point contact , valley splitting
Issue Date: 26-Jul-2009
Publisher: IEEE
Pages: 190-193
Abstract: We present a study of the conductance of quantum point contacts fabricated in AlGaN/GaN and Si/SiGe heterostructures. The investigated devices differ for typology (split gates and etched devices, respectively) and for the resulting potential profiles. We observe conductance quantization in multiple of 2e2/h units with superimposed anomalous plateaus and/or structures suggesting that correlation effects should be included in the description of our 1D systems.
