Research paper thumbnail of Erratum: “Band structures and thermoelectric properties of the clathrates Ba8Ga16Ge30,Sr8Ga16Ge30,Ba8Ga16Si30, and Ba8In16Sn30

All Seebeck coefficients reported in the paper are in error by a factor of Ϫ1. Thus in Fig. 7 of page 8065 and Fig. 12 on page 8068 the abscissa should properly read ϪS and not S. The purpose of this paper was to evaluate the potential use of these materials as thermoelectric devices through evaluation of the figure-ofmerit ZTϭS 2 T/. Thus, this error does not alter the important conclusions of this paper. However, in interpreting whether experimental materials are either p-or n-doped, the sign of S does matter. For p-doped materials SϾ0 while for n-doped materials SϽ0, and not the other way around. Thus there are several places in the text that should be revised.
