HERNANDEZ, C.  e  CHAUBET, C.. Impedancia longitudinal de un gas bidimensional de electrones en régimen de efecto Hall cuántico. Rev. mex. fis. [online]. 2009, vol.55, n.6, pp.432-436. ISSN 0035-001X.

We have measured the longitudinal impedance of a two dimensional electron gas in the quantum Hall effect regime. We have found smooth resonances of impedance for the middle of quantized plateaus and large resonances at the beginning and the end of the plateaus. Those resonances can be partially described using a simplified electrical circuit model. The analysis of the different experimental results shows a great influence of the experimental setup on the experimental measurements.

Palavras-chave : Impedance; quantum Hall effect; two dimensional electron gas.
