Abstract
The flatness and frequency dependence of the i = 2 and four quantized Hall resistance plateaus have been investigated. It was observed that for freque ncies up to 6.4 kHz, a flat region exists at the center of the plateaus whe re the relative resistance is constant to +/-2 x 10(-8), and its relative v alue has a linear frequency dependence of (0.119 +/- 0.001) (mu Omega/Omega )/kHz and (0.107 +/- 0.007) (mu Omega/Omega)/kHz for i = 2 and 4, respectiv ely.
