Abstract
Magnetoconductance measurements are presented for open electron resonators fabricated in a GaAs/Al(x)Gal(1-x)As heterostructure. Conductance peaks in the transport signal are observed, which are explained by the constructive interference of electron waves with the;Fermi wavelength. The application o f a perpendicular magnetic field causes a shift in the peak positions, whic h is explained by the combined effects of electron trajectory bending and t he Aharanov-Bohm phase shift.
