Application
Topological insulators are not conventional superconductors and cannot be used in ultra-efficient power lines because they can carry only a small amount of current, but they pave the way for a paradigm shift in the development of microchips, which will lead to new applications of sponomics in which electronic spin is used to carry information. Moreover, bismuth telluride is very easy to produce and use in practical applications. The 3D material can be manufactured by existing semiconductor technologies and is also easily doped, so that its properties can be tuned quite easily.
