What is bismuth telluride


Bismuth telluride is a gray powder with the molecular formula Bi2Te3. Bismuth telluride is a semiconductor material with good electrical but poor thermal conductivity. Although bismuth telluride is low risk, it can also be fatal if ingested in large quantities. However, this material can allow electrons to move on its surface without energy consumption at room temperature, bringing a leap in the operating speed of chips and even significantly improving the operating speed and efficiency of computer chips. The National Accelerator Laboratory of the Stanford Linear Accelerator Center (SLAC) of the United States Department of Energy and scientists from the Stanford Institute of Materials and Energy Sciences (SIMES) of Stanford University have worked together. On June 11, 2009, in the online edition of Science Letters, American physicist Chen Yulin and others published a test report on the electronic properties of bismuth telluride. The test results show that this material has the apparent characteristics of a topological insulator, allowing electrons to flow freely on its surface without losing any energy. Topological insulators are not conventional superconductors, nor can they be used for ultra-efficient power lines, as they can only carry a small amount of current. However, they pave the way for the paradigm shift in microchip development, leading to a new application of spintronics, using electron spin to carry information.

Moreover, bismuth telluride is easy to produce and use in practical applications. This three-dimensional material can be manufactured using existing mature semiconductor technology and easily doped, making it relatively easy to tune its performance.
