Rex Tayloe's germanium laboratory treatment uses the Hall effect together with electrical conductivity to investigate electric charge carriers. A transverse voltage gives a sign-sensitive Hall response, while a longitudinal measurement supplies the conductivity. In a one-carrier model, combining the two separates carrier density from mobility: $R_H=1/(nq)$ and $\mu =|R_H|\sigma$. The interpretation requires a carrier model; simultaneous electron and hole contributions cannot generally be reduced to one unrestricted density estimate.^[ref]
