Herein we report the multilayered atomic model of Mo(110) analyzed by low energy electron diffraction (LEED) and consequent determination of the density of states (DoS) by density functional theory calculations. The surface relaxation of the atomic layers has been investigated for the adsorption of Sn. Different Sn structures depending on the coverage and conditions has been confirmed by LEED. It is evident from our experiment that, in order to compensate the contraction between 1 st and 2 nd atomic inter layers, the atomic inter-layer spacings between the 2 nd and 3 rd and between the 3 rd and 4 th inter atomic layers are found to be increased.
