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.
A nanoscale ring structure, typically referred to as an Aharonov-Bohm (AB) ring, with a quantum dot (QD) embedded in each arm serves a unit cell in a chain-like structure. The transmission through the device is presented as a function of the number of rings in the chain. Zeeman-splitting of the QD energy levels is also modeled and its effects are analyzed. Distinct transmission bands form as the ring...
