| Abstract: | The transport properties of a kind of quasi-periodical one-dimensional systemhave been studied. This system consists of a series of Fibonacci coupled quantum dots. Byusing the transfer matrix method, and taking account of the experiment techniques, theformalism of the electron transmission rate for the chain of quantum dots is proposed, andthe relationship between the conductance, magnetic field and voltage is discussed. From thenumerical results, it has been found that the transmission spectra of the system have richstructures, depending on the coupling among quantum dots. |
