We investigate the effects of spin-momentum locking on the interference and diffraction pattern of electrons in a double- or single-slit Gedankenexperiment. We show that the inclusion of the spin degree-of-freedom when coupled to the carrier’s motion direction — a typical situation occurring in systems with spin-orbit interaction — leads to modify the interference and diffraction patterns depending on the geometrical parameters system.
