Topological Insulators

Description: 

Topological insulators are materials that are insulating inside but can conduct electricity on the surface. The conduction process being spin-selective in these materials, make them increasingly important for ‘spintronics’ applications. In this class of materials, topological order of the surface states ‘protect’ the conducting surface from any kind of disorder or chemical passivation and give rise to dissipation less current states on surface. This new phase of matter has practical applications in electronics and quantum computing.
