Erratum: Structural Principles and Amorphouslike Thermal Conductivity of Na-Doped Si Clathrates [Phys. Rev. Lett. 85, 114 (2000)]
Year: 2001
Type: erratum
Abstract: In this Letter, we reported the thermal conductivity ͑k͒ of Na 8 Si 46 .Inadvertently, we had not corrected the data for the coefficient of contact thermal conductivity [1].When this is accounted for, the thermal conductivity is higher than reported in the Letter.Correct results are shown in Fig. 1.These results agree well with recent steady-state measurements for a pressed pellet of Na 8 Si 46 [2].The main conclusions of the Letter concerning structural principles of this clathrate remain the same, and the thermal conductivity is still amorphouslike (much smaller than for crystalline Si, and with a different temperature dependence).FIG. 1. Thermal conductivity for Na 8 S 46 .The error bars indicate typical experimental uncertainty.We are grateful to G. Nolas for useful discussions.
