FIG. 1.

A one-dimensional ring connected to two leads. The amplitudes and the transport directions of electron waves are denoted using arrows. The ring and the leads are made of same 2DEG and the entire structure is under an electric field which tunes the Rashba SOI parameter α.

FIG. 2.

(Color online) Differential conductance (left y-axis, red solid lines) and I-V curves (right y-axis, black dashed lines) at η = π/2 (strong coupling) and at η = π/6 (weak coupling). The conductance is in the unit of e 2/h. The radius of the ring a = 1 μm. The Rashba parameter α = 1.8 peV m, EF  = 75 meV, temperature T = 15 mK, and the effective mass me  ≈ 0.05 m.

FIG. 3.

(Color online) Differential conductance as a function of α (horizontal axis) and bias voltage V (vertical axis). The differential conductance is in the unit of e 2/h. The ring radius is a = 1 μm, temperature T = 15 mK, and me ≈ 0.05 m. In panels (a) and (b), EF  = 75 meV. In (c) and (d), the carrier density dependence of α is taken from Ref. 14.
