Inducing and tuning Kondo screening in a narrow-electronic-band system
Abstract
Non f-electron systems containing narrow electronic band and localized moments are a useful platform to study the Kondo lattice problem. Here, by using scanning tunneling microscopy, the authors show a transition from the insulating gap to a tuneable Kondo resonance in 1T-TaS2 by Pb intercalation.
