Atomic-level control of the thermoelectric properties in polytypoid nanowires†
Abstract
Thermoelectric materials have generated interest as a means of increasing the efficiency of power generation through the scavenging of waste heat. Materials containing nanometer-sized structural and compositional features can exhibit enhanced thermoelectric performance due to the decoupling of certain electrical and thermal properties, but the extent to which these features can be controlled is often limited. Here we report a simple synthesis of M2O3(ZnO)n (M = In, Ga, Fe)
