| 中文摘要 | electron transport in quantum coherent networks (interacting quantum waveguide arrays) is investigated theoretically with use of the scattering-matrix method. the scattering matrix for the basic unit of networks, the cross junction with square or rounded corners, is derived using the mode-matching technique, the overall scattering matrix for the network is obtained by the composition of the scattering matrices associated with each unit of the network, for a uniform network, the transmission spectra are calculated in the single-mode regime and an found notably dependent on the junction geometry. small reflection for the input terminal and uniform output for some output ports are obtained, which means that the quantum coherent network can be used as a distributing net for the electron waves. cross junctions with rounded corners of large radii are found to play a negative role in the device application of quantum coherent networks.
