中文摘要	we study theoretically the low-temperature electronic transport property of a straight quantum wire under the irradiation of a finite-range transversely polarized external terahertz (thz) electromagnetic (em) field. using the free-electron model and the scattering matrix approach, we show an unusual behaviour of the electronic transmission of this system. a sharp step-structure appears in the electronic transmission probability as the em field strength increases to a threshold value when a coherent em field is applied. we demonstrate that this effect physically comes from the inelastic scattering of electrons with lateral photons through intersubband transitions.
