Phase-driven current and quantum interference in the quantum Hall regime. II. More insight

Abstract

For pt.I see ibid., vol.3, p.215 (1991). Experimentally observed periodic oscillations in the magnetoresistance in the quantum Hall regime have been looked at in the framework of phase-driven current in narrow quantum-Hall samples. A modification to the previous calculation of the period of oscillations presented by this author is suggested and more insight into the phenomenon is given.
