Abstract Within the framework of the Floquet theorem, we have investigated single-electron photon-assisted tunneling in a double-well system using the transfer matrix technique. The transmission probability displays satellite peaks on the both sides of main resonance peaks and these satellite peaks originate from emission or absorption photons. The single-electron resonance tunneling can be control through changing applied harmonically potential positions, such as driven potential in wells, in barriers, or in whole double-well system. This advantage should be useful in the optimization of the parameters of a transmission device.

Online attention
Altmetric calculates a score based on the online attention an article receives. Each coloured thread in the circle represents a different type of online attention. The number in the centre is the Altmetric score. Social media and mainstream news media are the main sources that calculate the score. Reference managers such as Mendeley are also tracked but do not contribute to the score. Older articles often score higher because they have had more time to get noticed. To account for this, Altmetric has included the context data for other articles of a similar age.
