Interference of ballistic carriers in modulated quantum wires

We present the findings of the quantized conductance in a modulated quantum wire. The energy dependence of the transmission coefficient through a smoo th and modulated quantum wire is analyzed to define the role of elastic bac k scattering processes in the formation of the conductance oscillations and the current staircase, We demonstrate the oscillations of 1D conductance p lateaus as a function of drain-source voltage that are evidence of the inte rference effects caused by varying the energy of ballistic holes in the mod ulated quantum wire electrostatically created inside the silicon self-assem bled quantum well.
