The perylene core is at a large height of 3.37 Å and only a minute downward displacement of the functional anhydride groups (0.07 Å) occurs, yielding adsorption heights that agree with the sum of the involved van der Waals radii. Thus, already a single hBN layer leads to a decoupled (physisorbed) molecule, contrary to the situation on the bare Cu(111) surface. %F PUB:(DE-HGF)16 %9 Journal Article %U <Go to ISI:>//WOS:000460723900003 %R 10.1103/PhysRevB.99.121404 %U https://juser.fz-juelich.de/record/862154
