Phys. Rev. Lett. 77, 2538–2541 (1996)Observation of Chiral Luttinger Behavior in Electron Tunneling into Fractional Quantum Hall EdgesReceived 25 April 1996; published in the issue dated 16 September 1996 We measure the tunneling conductance ( G) and current-voltage ( I-V) characteristics for electron tunneling from a bulk doped-GaAs normal metal into the abrupt edge of a fractional quantum Hall effect. We observe clear power law behavior for both the I-V relationship and the conductance versus temperature. For tunneling into the ν = 1/3 edge the power law persists for one decade in V ( T), and 2.7 (1.7) decades in I ( G). This strongly indicates the 1/3 edge behaves like a chiral Luttinger liquid. In contrast, the ν = 1 edge is essentially linear, while the 2/3 edge is slightly nonlinear. © 1996 The American Physical Society URL:
