Learn what are conductors and insulators with these interactive learning resources for KS2 Science students aged 7-11 from BBC Bitesize.

In topological insulators the bulk of the material is insulating and cannot carry an electrical current, yet the surfaces of the same material are conducting. Their unique electronic properties make ...

WRITING in the Electrical Review of June 12, 1942, on the design of electrical insulators in relation to manufacturing processes, Dr. E. Rosenthal points out that methods of shaping ceramic ...

The findings were published in Nature Physics yesterday (February 3) under the title: "Spin-orbit-controlled metal–insulator transition in Sr2IrO4." "We have found a new way to switch electrical ...

2D topological insulators, also known as 2D quantum spin Hall insulators, are materials that are electrical insulators in the bulk but can conduct electricity extremely well on their edge via special, ...

Electrical insulators in the bulk, these materials have surface states that conduct electrons extremely well. In this video, Zahid Hasan of Princeton University in the US describes why topological ...

In 2004, researchers discovered something amazing: If the two materials, SrTiO3 and LaAlO3, both of which are electrical insulators, are joined together, a thin, electrically conducting region is ...
