Switchable molecular functionalization of an STM tip: from a Yu-Shiba-Rusinov tip to a Kondo tip

Cosme. G. Ayani, Fabian Calleja, Ivan M. Ibarburu +6

In this work we fabricate and characterize a functionalized superconducting (SC) Nb tip of a scanning tunnelling microscope (STM). The tip is functionalized with a Tetracyanoquinod…
