“…3 (2002) sence of carrier dispersion in the direction of a magnetic field directed perpendicular to the layers still does not destroy the quantum Hall effect, though a number of features appear [16]. Surface states can play a fundamental role in the existence of the quantum Hall effect in three-dimensional systems [17]. The narrow gap semiconductors InSb and Hg 0.8 Cd 0.2 Te show quantum Hall effect-like behavior [18,19].…”

The temperature dependence of the resistivity and the Hall effect in the range 0.3-300 K, and the Shubnikov-de Haas effect have been investigated in Sn-doped p-(Bi 1Àx Sb x ) 2 Te 3 ð0 x 1:0Þ single crystals. Doping of (Bi 1Àx Sb x ) 2 Te 3 with tin showed that Sn exhibits acceptor properties in all crystals. The anomalous temperature and magnetic field behavior of the Hall coefficient was explained quantitatively by a model, which involves the complicated two-valence band structure of p-(Bi 1Àx Sb x ) 2 Te 3 . The quantization of the Hall resistivity r H in the form of plateaus in the dependence of r H on the magnetic field B is observed. The minima of the transverse magnetoresistivity r correspond to the start of plateaus. The oscillation of r H is due to the presence of a carrier reservoir. An impurity resonant band with a high density of states in Sb 2 Te 3 or the second lower valence band with a higher hole effective mass in (Bi 1Àx Sb x ) 2 Te 3 serves as the reservoir. The valence band structure of (Bi 1Àx Sb x ) 2 Te 3 is also discussed.

“…The results of the experiment on Note that the field B pi , at which the phase inversion occurs, rapidly increases at lowering the temperature. This obviously is reflected in the temperature dependence of the oscillation amplitude, leading to drastic deviations from the conventional LifshitzKosevich behavior [55,56]. Indeed, according to the data in Fig.…”

The low-temperature charge-density-wave (CDW) state in the layered organic metals α-(BEDT-TTF) 2 MHg(SCN) 4 has been studied by means of the Shubnikov -de Haas and de Haas -van Alphen effects. In addition to the dominant α-frequency, which is also observed in the normal state, both the magnetoresistance and magnetic torque possess a slowly oscillating component. These slow oscillations provide a firm evidence for the CDW-induced reconstruction of the original cylindrical Fermi surface. The α-oscillations of the interlayer magnetoresistance exhibit an anomalous phase inversion in the CDW state, whereas the de Haas -van Alphen signal maintains the normal phase. We argue that the anomaly may be attributed to the magneticbreakdown origin of the α-oscillations in the CDW state. A theoretical model illustrating the possibility of a phase inversion in the oscillating interlayer conductivity in the presence of a spatially fluctuating magnetic breakdown gap is proposed.
