Nanostructuring in thermoelectric β‐Zn 4 Sb 3 has been observed by Protima Rauwel et al. ( pp. 1652–1657 ). A variation in the Zn:Sb ratio brings about a phase separation not only at the microscale but also at the nanoscale. Through the technique of electron microscopy, the authors have been able to qualify the phase separation at both scales. Depending on the Zn:Sb ratio nanoprecipitation of ZnSb (Zn:Sb = 1.28), nanovoids (Zn:Sb = 1.30) or nanoprecipitation of Zn (Zn:Sb = 1.36) occurs. Stacking faults (centre figure) in β‐Zn 4 Sb 3 are also present for very high starting Zn contents.
