Descrição: Resonant tunneling through edge states bounded around an antidot in quantum Hall (QH) regime has been investigated and we have found multiple frequency oscillations in a resonant tunneling through an antidot. We have measured resistance as a function of magnetic field and front gate voltage and found the periodic oscillation in the ν = 2 to 1 transition regime. It is related that discrete energy levels are formed in the edge states around the antidot [1]. Not only single peaks but also some split peaks are seen in our data. Fourier power spectrum of the data shows double and triple frequency peak. (© 2005 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
