Abstract :
Multiple, serially-connected nanoscale rings are analyzed using a tight-binding computational algorithm which allows calculation of the transmission and current characteristics of the system as a function of energy and external magnetic flux. Results show the role of bilateral symmetry in the system response to imposed flux, which can shift the system from metallic to semiconducting.
