## Description

- description: To probe the sources of scattering, we use a cooled scanning probe
    microscope (SPM) to image the flow of electrons in a MoS2 Hall bar sample at 4.2
    K. Capacitive coupling to the SPM tip changes the electron density below and scatters
    electrons flowing nearby; an image of flow can be obtained by measuring the change
    in resistance between two contacts as the tip is raster scanned across the sample.
    We present images of current flow through a large contact that decay exponentially
    away from the sample edge. In addition, the images show the characteristic “bullseye”
    pattern of Coulomb blockade conductance rings around a quantum dot as the density
    is depleted with a back gate. We estimate the size and position of these quantum
    dots using a capacitive model.
