Abstract
A theoretical analysis of the electron transport properties of plain and bumpy jelliumnanowires suspended between semi-infinite jellium electrodes is carried out, and thepossibility of the experimental observation of the conductance oscillation witha period longer than the two-atom length is discussed. In both the nanowires,the transmission trace as a function of the nanowire length exhibits oscillatorybehaviour. The period of the oscillation of the plain nanowire corresponds toπ divided by the Bloch wavenumber of the electrons in the nanowire region. However, theperiod of the oscillation of the bumpy nanowire results in the least common multiple ofπ divided by the Bloch wavenumber and the geometric period of the nanowire. Our resultindicates that the conductance oscillation with a period longer than the two-atom lengthcan be experimentally observed if nanowires without any defects are formed in experiments.
