Abstract

The T dependence of both the width and the peak value G_p of a conductance peak on the i = 2 integer quantum Hall (IQH) plateau was measured. The observed G_p ∝ 1/T dependence is consistent with resonant tunneling through only one nondegenerate QAD-bound state, and rules out the regime of tunneling through several degenerate states. For the first time, three conductance peaks per ø₀ were observed on the i = 3 plateau.
