摘要
The transmission through quantum wires is studied within a noninteracting model taking into account the geometry of cleaved edge overgrowth devices. We show that the junction between wide contact and narrow wire has almost no influence on the transmission through these devices while a potential step between contact and wire strongly effects the conduction. Our results are compared with recent experimental findings.
