概要
- 論文の詳細を見る
Magnetic field and Fermi energy dependences of conductance in a quantum wirewith a small ring geometry are calculated numerically with the use of the coupledchannel method. As a function ol' the Fermi energy or magnetic field, the conductance shows various pattern behaviours, of which the origin is discussed on the basisof the numerical results. The conductance shows oscillations as a function ofmagnetic flux passing through the effective area enclosed by the ring part. A value ofthe oscillation period as a function. of the magnetic flux is given by cl:?.,= h / e approximately if the effective area enclosed by the ring part is estimated as an area enclosedby the potential energy minimum curve.[Aharonov-Bohm oscillation, ballistic transport, quantum rimng, mesoscopic l] systeml
