Euclidean action at tunneling in magnetic field
freetext keyword: Quantum mechanics tunneling; Semiclassical theories in quantum mechanics; Traversal time
type: Thing
abstract: A state of an electron in a quantum wire or a thin film becomes metastable, when a static electric field is applied perpendicular to the wire direction or the film surface. The state decays via tunneling through the created potential barrier. An additionally applied magnetic field, perpendicular to the electric field, can increase the tunneling decay rate of an excited state by many orders of magnitude. This happens when the state in the wire or the film has a velocity perpendicular to the magnetic field. According to the cyclotron effect, the velocity rotates under the barrier and becomes more aligned with the direction of tunneling. This mechanism can be called cyclotron enhancement of tunneling. © 2009 World Scientific Publishing Company.
