Abstract :
The flatness and frequency dependence of the i=2 and four quantized Hall resistance plateaus have been investigated. It was observed that for frequencies up to 6.4 kHz, a flat region exists at the center of the plateaus where the relative resistance is constant to ±2×10-8, and its relative value has a linear frequency dependence of (0.119±0.001) (μΩ/Ω)/kHz and (0.107±0.007) (μΩ/Ω)/kHz for i=2 and 4, respectively
