Abstract
We consider conductance mapping of systems based on the two-dimensional electron gas with scanning gate microscopy using two or more tips of an atomic force microscope. The paper contains the results of numerical simulations for a model tip potential. In addition, a few procedures are proposed for the extraction and manipulation of ballistic transport properties. In particular, we demonstrate that the multitip techniques can be used to obtain a readout of the Fermi wavelength, to detect potential defects, to filter specific transverse modes, and to tune the system into resonant conditions under which a stable map of the local density of states can be extracted from conductance maps using a third tip.
