The Hall effect remains a puzzle. The theoretical explanation of the sign anomaly depends on the relative phases of the wavefunctions on adjacent sites. The phases are only correlated if the electron moves from one silicon atom to its nearest neighbor. However, the mobility edge in a-Si H is far from the... 

A similar agreement is also obtained for most of the substances which have been investigated by Kapitza. Deviations are exhibited only by substances of the bismuth type, and by semi-conductors like Ge. In neither case are the anomalies very astonishing, as bismuth behaves quite differently from the other metals as regards all magnetic phenomena (e.g. diamagnetism, the Hall effect), so that we are driven to conclude that in its case some other phenomena which hitherto have not been taken into consideration must play a part. In the case of semi-conductors, the idea of free electrons,... 

Hall effect is another important transport phenomenon and has been extensively studied in amorphous semiconductors. The Hall effect studies also assumed importance because of an anomaly observed between the sign of the charge carriers indicated by Hall coefficient and S in amorphous semiconductors. The Hall coefficient Rh is given by.

Another anomaly in the ultrasonic attenuation of c-axis shear waves has been detected at 95.5 K by the same group (Lee et al. 1975). Applied fields along both a- and c-directions shifted the peak to higher temperatures. Volkov et al. (1974) found an extremum in the a-axis susceptibility (but not in c) together with an anomaly in the Hall resistivity at 93 K. The origin of these effects is not clearly understood, but it is presumably reflected in the magnetization curves (fig. 6.7) as the disappearance, between 95.2 K and 100.2 K, of the transition at Additional neutron diffraction studies extending Koehler s examination beyond 75 K would be helpful here.
