摘要
The authors measured Aharonov-Bohm resistance oscillations [Phys. Rev. 115, 485 (1959)] in a shallow two-dimensional GaAs hole ring structure, defined by local anodic surface oxidation. The amplitude of the oscillations is about 10% of the ring resistance, the strongest seen in a hole system. In addition the authors observe resistance oscillations as a function of front gate bias at zero magnetic field. They authors discuss the results in light of spin interference in the ring and possible applications to spintronics. (c) 2007 American Institute of Physics.
