摘要: We propose a new method for atomic-scale imaging of spatial current patterns in nanoscopic quantum networks by using scanning tunneling microscopy (STM). By measuring the flowing from STM tip into one leads attached to network as function position, obtains an atomically resolved image "current riverbeds" whose structure reflects coherent flow electrons out equilibrium. show that this can be successfully applied variety topologies and is robust against dephasing effects.
