Paper Abstract

We present the findings of quantized conductance (QC), Coulomb staircase (CS) and local tunneling spectroscopy (LTS) techniques which reveal the single-hole confinement and charging phenomena in the smooth and modulated quantum wires created electrostatically inside self-assembly longitudinal (SLQW) and lateral (SLaQW) silicon quantum wells. The current- voltage (CV) characteristics obtained are in a good agreement with the data of the theoretical calculations taking account of quantum interference effects in the field-dependent value of the transmission coefficient through the quantum wires that exhibit the different degree of a modulation.
