%X Using the method developed by Gurvitz S.A for solving Shrodinger equations and numerical calculation, we investigate the driving frequency dependence of the current of periodic coupled quantum wells.The results indicate that the stable current increases with the driving frequency on condition of the driving frequency being smaller than the energy difference between wells. Otherwise, the stable current will decrease with increasing driving frequency. Therefore,the current of the system can be controlled by the driving frequency.
