Abstract
An aqueous solution method is developed for the facile synthesis of Cl-containing
SnSe 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 ...
An aqueous solution method is developed for the facile synthesis of Cl-containing
SnSe 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
high performance n-type SnSe thermoelectric materials.
