Figure 2.

Scanning electron micrograph of a sample shaped using FIB milling. A cubic like block has been welded at the end of an AFM cantilever. The block is glued at the extremity of the lever as in the case of near-field radiative heat transfer measurement [11]. In the case of Casimir or electrostatic forces measurement the block should be welded on the side of the cantilever
