Planning the electron traffic in semiconductor networks: A mesoscopic analog of the Braess paradox encountered in road networks
arXiv:1312.1885 · doi:10.1063/1.4848369
Abstract
By combining quantum simulations of electron transport and scanning-gate microscopy, we have shown that the current transmitted through a semiconductor two-path rectangular network in the ballistic and coherent regimes of transport can be paradoxically degraded by adding a third path to the network. This is analogous to the Braess paradox occurring in classical networks. Simulations reported here enlighten the role played by congestion in the network.
