nanoparticles in 10 g quantities per batch. The particle size and Cl concentration of the
nanoparticles can be efficiently tuned as a function of reaction duration. Hot pressing
produces n‐type Cl‐doped SnSe nanostructured compacts with thermoelectric power factors
optimized via control of Cl dopant concentration. This approach, combining an energy‐
efficient solution synthesis with hot pressing, provides a simple, rapid, and low‐cost route to …
