Abstract
We study the ballistic motion of electrons in an array of submicron circular cavities, fabricated by electron beam lithography and dry etching techniques. Pronounced magnetoresistance oscillations are observed that can be understood in terms of internal magnetic focusing or commensurability between the electron trajectories and the geometry of the cavities. The depletion distance in the two-dimensional electron gas caused by the dry etching process can be deduced by analysis of the resonance peak positions within a simple magnetic focusing picture.
