NettetCurrent that is caused by electron motion is called electron current and current that is caused by hole motion is called hole current. Electron is a negative charge carrier whereas hole is a positive charge carrier. At absolute zero temperature intrinsic semiconductor behaves as insulator. However, at room temperature the electrons … NettetFrom the author: The free electrons and holes are mobile, they are responsible for the conduction of electricity. When the free electrons recombine with holes, the electron is still there, but it is no longer mobile, it no longer conducts electricity. So in that sense, we have 'lost' charge carriers. Comment. NettetAs nouns the difference between electron and hole is that electron is the subatomic particle having a negative charge and orbiting the nucleus; the flow of electrons in a conductor constitutes electricity while hole is a hollow place or cavity; an excavation; a pit; an opening in or through a solid body, a fabric, etc.; a perforation; a rent; a fissure. magasin gamestop france
