Fast pulsed photoemission from a double quantum well on a dielectric substrate as a dynamic process of inverse LEED leading to the generation of a charge and current density wave
Yu. G. Peisakhovich, A. A. Shtygashev
Within the framework of the rigorous quantum theory of the atomic photoeffect and the scenario of photoemission from a crystal as an inverse LEED process, pulsed photoemission from…

Formation of probability density waves and probability current density waves by excitation and decay of a doublet of quasistationary states of a three-barrier heterostructure upon scattering of gaussian wave packets
Yu. G. Peisakhovich, A. A. Shtygashev
A numerical-analytical simulation of scattering by a three-barrier heterostructure of an electronic Gaussian wave packet, the spectral width of which is on the order of the distanc…
