Join us at the International Thermal Conductivity Conference (ITCC) and the International Thermal Expansion Symposium (ITES).
High-quality bismuth telluride crystals having a thickness of only a few atoms were prepared by a method similar to that for graphene mechanical exfoliation. The potential for these materials to be used as thermoelectric materials was then investigated. It was found that the properties of these materials could be fine-tuned by altering the thickness, or the sequence of atomic planes. “Stacked superlattices” were formed using these atomic films, and these ...
