Abstract
Low temperature scanning tunneling microscope techniques are applied to study statistical properties of the BiO plane in 2212 high-Tc single crystals. The correlation functions of height deviations in x and k -spaces have been numerically obtained. Long range power law correlations have been found and attributed to half lattice cell jumps of known height in the c direction. Analysis of the correlation function in k-space reveals two modulating superstructures in the b direction. The most pronounced structure is the well known superstructure with period a1 ≈ 27 Å. The other one has period a2 ≈ 58 Å which is a little more than twice the period of the main superstructure.
