WebResonant tunneling is the process whereby an electron incident from one side of a double barrier structure traverses the structure at or near an energy corresponding to one of the quasi-bound, or metastable, levels in the quantum well. The fundamental requirement for this process to occur is quantization by spatial confinement. As shown in Fig. 1, the nth … WebIn 1929, physicist Oskar Klein [1] obtained a surprising result by applying the Dirac equation to the familiar problem of electron scattering from a potential barrier.
