The thermoelectric power of the gamma-phase alloys in the copper-zinc system has been measured at room temperature relative to pure copper. The thermoelectric power is found to be a smooth function of composition except in the range between 64.4 and 65.4 at.% Zn where there is a discontinuous change.
Analysis based on a band-approximation suggests that such a discontinuity can be attributed to the extinction of a band of electron holes or the initiation of a band of overlap electrons. However, there is a practical difficulty in distinguishing between the two processes, since the discontinuity occurs in the same and negative direction in either case. This difficulty was overcome with recourse to extra information concerning the Brillouin zone of the gamma-phase, and the discontinuity was interpreted in terms of the electron overlap across the {411} plane.
