Several studies have probed the influence of the adsorption on metal-supported hBN layers on the electronic structure of large organic molecules, namely their frontier orbitals, by PES [36] or STS [37][38]. However, to the

This value is consistent with that measured on copper phthalocyanine (CuPc) adsorbed on Au(111) [24]. Adsorption on Ag(111) and Cu(111) surfaces It is well known for large organic molecules

At these sites the molecules can interact with the atoms of the step layer as well as terrace layer and become more strongly bound [56]. Furthermore, they can exhibit one-dimensional motion when diffusing

Despite recent progress in computing free energies and an increase in computer power, it is still not trivial to calculate free energies of processes for large

Nevertheless it is vital to gain better understanding of the free-energy landscape and the competing interactions at higher temperatures. Many experiments
