A novel method for rapid preparation of Bi 2 Te 3 nano-sized powders with an average particle size of about 70 nm was developed. A starting powder mixture consisting of Bi 2 Te 3 coarse particles of ∼5 mm was ground using cryogenic grinding in the liquid nitrogen. For comparison, the conventional high-energy ball milling was used to prepare the Bi 2 Te 3 nano-sized powders.
