So fat, we have justified that the two-dimensional Coulomb interacting electron gas in the presence of a strong magnetic field can be described effectively in terms of a 'free'

at high temperatures TCNQ carriers are electron-like and HMTSeF carriers are hole-like, thus a larger mobility of the HMTSeF electrons may account for the sign of

In a recent publication Nizhankovskii et a1 (9) have investigated the effect of magnetic field on the chemical potential of electrons in GaAs H. This analysis corresponds

Although the observed plateau values of the Hall resistance are sample-independent, the very occurrence and the width of the plateaus are attributed to localized electron states
