On the other side, the C50, C60, and C70 fullerenes are physisorbed onto phosphorene with positive adsorption energies of up to 1.0 eV, denoting stable adsorption that compares to the stability reached by C36 and C40 via chemisorption (Fig. ). Note also adsorbed fullerenes could be further stabilized by neighboring molecules onto phosphorene through strong moleculemolecule interactions, arising two-dimensional self-assembly in the physisorption regime as reported for C60 adsorption . Compared to our results, periodic vdW-KBM calculations and molecular dynamics simulations have reported non-covalent Phos-C60 complexes with Eads values of 0.7 and -1.0 eV, respectively ; then, our results agree with previous reports. Additionally, UV-VIS-NIR absorbance, temperature scanning tunneling microscopy, and scanning tunneling spectroscopy measurements indicate that C60 molecules physically adsorb on phosphorene, where desorption occurs with annealing 400 K . As can be seen, Eads=0.9 eV for Phos-C60
