This is a simulation of a charged particle travelling through a nanoscale layered semiconductor structure based on the transfer-matrix method.
For certain configurations of the potential profile, the transmittance may exhibit a resonance peak at energies below the barrier height due to the quantum tunnelling. This is the case in the default setting of the app below, with an electron travelling through two 2-nm wide rectangular barriers in a gallium arsenide (GaAs) layer.
