Purdue University doctoral student Yang Xu, lead author of a new research paper on "topological insulators," an emerging class of materials that could make possible "spintronic" devices and practical ...

Scientists have long dreamed of making molecular electronics, building one-dimensional strings atom by atom to create new circuits even smaller than today’s tiniest silicon structures. Shrinking ...

A topological insulator is a material with a structure that conducts electrons in a unique way. The bulk of the material is an insulator, completely preventing the flow of electrons through it.

For the first time, physicists have observed novel quantum effects in a topological insulator at room temperature. This finding opens up a new range of possibilities for the development of efficient ...

Topological insulators (TIs) have fundamentally reshaped our understanding of materials by introducing robust boundary states arising from bulk topological invariants. Extending this paradigm, ...
