High-performance Bulk Thermoelectrics with All-Scale Hierarchical Architectures

Nature 489, 414–418 (2012); doi:10.1038/nature11439 In this Letter, the units of thermal conductivity on the y-axes of Fig. 2d and e should be W m−1 K−1 and the y-axis label of Fig. 3d should be ‘Count (%)’. Figures 2 and 3 of the original paper have been corrected online.
