In　this　work,　with　the　completely　asymmetric　terahertz　(THz)　irradiation,　electron　transport　through　a　two-level　InAs　quantum　dot　is　theoretically　discussed.　The　Coulomb　interaction　in　this　system　is　compared　with　the　energy　difference　between　the　two　energy　levels　and　is　finite　contrasted　with　the　Microwave　Field　system.　We　investigate　the　average　current　trend　with　the　change　of　Coulomb　interaction　and　the　THz　irradiation　strength.　Our　results　reveal　that　there　exists　the　photon-electron　pump　effect　at　the　Coulomb　interaction　related　energy　level,　and　demonstrate　Fano-like　resonance　in　the　low　THz　field　strength　due　to　the　presence　of　the　photon　induced　excited　state　resonance.　We　also　find　that　the　Fano-like　resonance　can　be　suppressed　with　increasing　the　temperature.　(C)　2014　AIP　Publishing　LLC.
