WebFeb 18, 2024 · Idea 0.1. A quantum spin Hall effect, is. a variant of the spin Hall effect where quantum effetcs play a role;. a variant of the quantum Hall effect where spin-orbit coupling in the underlying material (typically a topological insulator) takes the role of the external magnetic field.. The fact that no external field is needed in a quantum spin Hall effect … The Hall effect is due to the nature of the current in a conductor. Current consists of the movement of many small charge carriers, typically electrons, holes, ions (see Electromigration) or all three. When a magnetic field is present, these charges experience a force, called the Lorentz force. When such a magnetic field is absent, the charges follow approximately straight paths between collisions with impurities, phonons, etc. However, when a magnetic field with a perpendicular co…
