We investigate the nature of electronic states and transport properties of a one-dimensional Quantum Wire
(QW) with side-coupled Quantum Dots
(QD) within a single-band non-interacting tight binding framework. The Real Space Renormalization Group (RSRG) method and the standard Green's function technique are used to compute the local density of states (LDOS) and the two-terminal transport characteristics for the system. The effects of the side-attached QDs on the LDOS spectrum and on the transport properties of the system are analyzed. We propose that our analysis can be inspiring in designing low-dimensional switching devices.
