Query: Imaging signatures of the local density of states in an electronic
  cavity   We use Scanning Gate Microscopy to study electron transport through an open,
gate-defined resonator in a Ga(Al)As heterostructure. Raster-scanning the
voltage-biased metallic tip above the resonator, we observe distinct
conductance modulations as a function of the tip-position and voltage. Quantum
mechanical simulations reproduce these conductance modulations and reveal their
relation to the partial local density of states in the resonator. Our
measurements illustrate the current frontier between possibilities and
limitations in imaging the local density of states in buried electron systems
using scanning gate microscopy.
