Physical Origins of Fine Structure in the Resonant Tunneling through Laterally Confined 1D-0D-1D Structures

Abstract: We use helium atom scattering to investigate the structures formed by Li adsorption onto Cu(001) in the 0-2 ML regime. Submonolayer growth at 180 K proceeds through a sequence of ordered overlayers, including a c(2 × 2) structure at 0.5 ML and a series of 'ladder' superlattices around 0.6 ML. Beyond 1 ML, incommensurate, three-dimensional Li islands develop. A quantum close-coupled scattering analysis is performed to study the empirical He-surface potential of the structurally heterogeneous ladder structures. … Show more

“…16,26,27,29,32,33,34,35 With this method, one can in principle model the electron transport through a device with a given potential profile V(x,y,z) with arbitrary accuracy. In this work we study the effects induced on the device characteristics by a variation of the lateral confining potential, corresponding to the variation of a gate voltage.…”

“…This method has been successfully tested and used in recent years for the study of a variety of systems including e.g. disordered quantum wires [30,31], antidot arrays [37], disordered Aharonov-Bohm interferometers [39], quantum dot structures [40][41][42][43], quantum coherent networks [44], coupled quantum wires [45] etc. The method has, as far as we know, not been used for studies of electron transport in three-terminal structures, and a formulation and implementation of the method has not yet been demonstrated.…”
