Is selenium a conductor or insulator

WitrynaConductor. Insulator. Materials that permit electricity or heat to pass through it. Materials that do not permit heat and electricity to pass through it. A few examples of a conductor are silver, aluminium, and iron. A few examples of an insulator are paper, wood, and rubber. Electrons move freely within the conductor. Witryna2 dni temu · The prepared material is a 3D topological insulator, a new state of matter with insulating energy gaps in the bulk and gapless conducting edge or surface states. The irradiation displaced atoms causing the transformation of the surface from a crystalline to a disordered glassy state.
