Performance
Bismuth telluride powder is a semiconductor material, with good conductivity, but poor thermal conductivity. Although the risk of bismuth telluride is low, but if a large number of intake is also a fatal danger but this material can allow electrons at room temperature without energy in the surface of its movement, which will bring the chip speed of operation, even Can greatly improve the computer chip running speed and efficiency.
