Sentences with phrase «moving electrons conduct»

Not exact matches

This ability to switch conductivity is possible because some of their electrons can move from lower - energy insulating states to higher - energy conducting states when subjected to an input of energy.

Quantum mechanics governs, for example, how fast — and if at all - electrons can move through a material and, thereby, determine whether the material is a metal which conducts an electric current or whether it is an insulator which can not conduct a current.

This ability to switch conductivity on and off is possible because some of a semiconductor's electrons can move from lower - energy insulating states to higher - energy conducting states when subjected to an input of energy.

The previously freely moving electrons come to an abrupt halt and the material loses its conducting properties.

Step edges on topological crystalline insulators may lead to electrically conducting pathways where electrons with opposite spin spin move in converse directions — any U-turn is prohibited.
