FIELD: physics.
SUBSTANCE: invention discloses a structure consisting of a base on which there are nanotubes having known geometrical and physical parametres and fullerenes C60 which form a separate single-layer spatially bordered film on the surface of the base. The technical result is using nanotubes which are ideal cylindrical objects with a nanosized diametre, which enables use of the test structure for accurate determination of the rounded radius of a needle point in atomic-force and tunnel microscopes.
EFFECT: use of single-layer fullerenes C60 provides a measure of length on the test structure for vertical and lateral displacements of the probe point relative the base with known accuracy.
