Scanning tunnelling microscopy of cleaved bismuth surfaces at low temperatures
revealed the existence of identical thin twin interlayers, embedded in the
main crystal. The interlayers were strictly ordered along the surface atomic
rows. They were of the macroscopic lengths of the order of one micrometre. The
width of interlayers was about 
. It corresponds nearly to the
distance at which the height gained due to the tilt of twin interlayer atomic
lattice with respect to the main crystal surface reaches the interplanar
spacing in the [0001] direction, i.e. 
. Hence the width
"quantization" is connected with the matching of atomic planes at both
sides of twin interlayer.
