Abstract : Due to their geometry and asymmetric transport properties, carbon nanotube Y-junctions make it possible to create three-terminal nanoelectronic devices and fully nanoscale device networks. To understand the propagation of electron waves in these nanoscopic "wave guides", we have simulated the STM images of such systems by calculating the transversal propagation of electronic wave packets through an STM model. The STM tip acts as a local injection source, the variation of the probability density along the branches of the Y-junction gives information about the wave packet reflections and localized states.
