Abstract
The disclosure relates to a method for making an iron telluride including placing Fe, Bi, and Te in a reacting chamber as reacting materials. The reacting chamber is evacuated to be a vacuum with a pressure lower than 10 Pa. The reacting chamber is heated to a first temperature of 700 degrees Celsius to 900 degrees Celsius and keeping the first temperature for a period of 10 hours to 14 hours. Then the reacting chamber is cooled to a second temperature of 400 degrees Celsius to 700 degrees Celsius within 60 hours to 75 hours and keeping the second temperature for a period of 40 hours to 50 hours, to obtain a reaction product including a FeTesingle crystal. The FeTesingle crystal is separated from the reaction product.
