Scaling of the Integral Quantum Hall EffectA review is given of recent experiments testing the two-parameter scaling theory of the integral quantum Hall effect. The temperature driven flow diagram in the σ.(T) vs. σ.(T) of the two-dimensional electrons in InGaAs-InP, measured from 10K to 50mk, shows scaling behavior and is consistent with the theory.作者: originality 時間: 2025-3-23 12:52
Calculation of the Conductivity of Two-Dimensional Disordered Systems in the Presence of a Strong MaDue to the discovery of the quantized Hall effect (QHE) [1] the interest in the theoretical calculation of the transport properties of inversion layers in strong magnetic fields has increased considerably during recent years [2]. Of particular interest is the inclusion of a random potential.作者: 話 時間: 2025-3-23 15:31 作者: drusen 時間: 2025-3-23 18:30
A New Quantum Effect in the Transverse Magnetoresistance of Two-Dimensional Conductors with a NarrowA new type of quantum steps has been observed in the transverse magnetoresistance of a two-dimensional conductor, having a narrow constriction in the width of the conducting channel. The quantized resistance values are integer multiples of h/(2n.e.), where n. is related to the number of quanta h/(2eB) of magnetic flux through the constriction.作者: 侵略 時間: 2025-3-24 00:20
