A Cross-Section of Nano-Crystalline Bismuth Antimony Telluride Grains (image) Boston College Share Print E-Mail Caption A cross-section of nano-crystalline bismuth antimony telluride grains, as viewed through transmission electron microscope. Colors highlight the features of each grain of the semiconductor alloy in bulk form. A team of researchers from Boston College and MIT produced a major increase in thermoelectric efficiency after using nanotechnology to structure the material, which is commonly used in industry and research.
