Experimental details
Usual salt used for cooking, or Sodium Chloride, has a cubic crystal structure. Being cleaved it strips step-like terraces, which can be only 0,56nm high (NaCl lattice constant). This 2µm x 2µm x 0,1µm AFM image clearly shows the structure of freshly cleaved Sodium Cloride crystal revealing its smallest steps corresponding to single interatomic lattice layers.
