Distinct evolution of vibrational characteristics with thickness that is revealed in the phonon density of states (PDOS) witnesses a textbook transition from 2D to 3D lattice dynamics. For the thinnest films of 1 and 2 ML, the low energy part of the PDOS followed a linear dependence in energy that is characteristic for 2-dimensional systems. This dependence gradually transforms with thickn","authors_text":"A.I. Chumakov, A. Kozio{\\l}-Rachwa{\\l}, D. Wilgocka-\\'Sl\\k{e}zak, J. Goniakowski, J. Korecki, K. Freindl, K.
