Ordering up better conductivity Improving a thermoelectric material's ability to convert heat electricity involves optimizing one property without changing another in detrimental way. Roychowdhury et al. found that cadmium doping of silver antimony telluride enhances cationic ordering, which simultaneously improves electric properties and helpfully decreases thermal (see the Perspective by Liu Ibáñez). This strategy markedly could be used for other materials. Science , this issue p. 722 ; see also 678
