Abstract
We present results of conductance measurements of ultranarrow inversion layers in which averaging has resulted in what we believe to be a clear observation of a quasi one-dimensional density of states. A 0.2-μm-period grating gate is used to produce 250 inversion lines in parallel, each of which is Å50 nm wide and 10 μm long. Summing the conductance of these lines results in a signal-to-noise improvement of of (Å16) which has enabled the observation of the quasi one-dimensional conductance oscillation.
