Figure 2

Theoretical friction vs load curves for two different materials in contact with an AFM tip. a) Contact 1 has a higher surface adhesion than contact 2 (γ1 > γ2) but the same shear strength. b) Shear strength of contact 1 is higher than that of contact 2. c) Shear strength of contact 1 is lower than contact 2; adhesion of contact 1 is higher than contact 2.
