Kerstin Petermann,Thomas Kohnent contact in a two-dimensional electron gas. Two alternative points of view are emphasized. On the one hand, the experiment is a realization of electron optics in the solid state. The three basic building blocks are a coherent and monochromatic point source/detector, an electrostatic mirror with lit

The method is based on reflectance and transmittance measurements, in particular with polarized light at oblique incidence. Thus the interaction of the electromagnetic waves with thin fil
