Physical Review B
The interaction between an Ir tip and an Ir sample was investigated during normal tunneling operation of the scanning tunneling microscope. Force gradients compatible with metallic adhesion were observed within a range of 2 before making contact. Based on the theory of metallic adhesion, a scaling relation is derived which allows the tip geometry and the characteristics of the interaction to be accounted for in a systematic manner. © 1990 The American Physical Society.
