Interfacial and intermolecular interactions determining the rotational orientation of C60 adsorbed on Au(111)

Large area self-ordered parallel C60 molecular nanowire arrays on Si(110) surfaces

“…The rings of the Si pentagons serve as anchor pits where C 60 molecules can be hosted because there is a perfect geometric match between the pentagon of the C 60 molecule and the Si pentagon on the upper terraces of Si(110). Moreover, the 6:6 bond of the C 60 would align with the Si pentagon, similar to the stabilization of the relative orientation of adjacent molecules by the alignment of a 6:6 bond of one C 60 molecule opposite to a pentagonal ring of the adjacent molecule[38]. Thus, the Si pentagon acts as an anchor pit for the selective adsorption of C 60 molecule and ensuing the self-organized growth of molecular NWs along the periodic upper terraces of a Si(110) surface to form a highly regular parallel molecular NW array.…”

Rotational superstructure in van der Waals heterostructure of self-assembled C60 monolayer on the WSe2 surface

“…28 The interfacial interaction of C 60 with other 2D TMDCs has been shown to result in doping, with pdoping occurring for WSe 2 in particular, 29 and with graphene has led to charge transfer and increased carrier mobility. 30 While the self-assembly of C 60 molecules on metal surfaces like Cu, [31][32][33][34] Au, 32,[35][36][37][38][39][40][41][42] and Ag 32,35,40 has been widely studied by STM, their behavior on 2D material substrates is relatively unknown aside from some studies on graphene. 15,[43][44][45][46] The electronic and physical structure of the substrate has played an important role in these earlier works, and is also expected to be crucial in the case of WSe 2 .…”

Orientation Ordering and Chiral Superstructures in Fullerene Monolayer on Cd (0001)

“…The individual molecules marked by red, green, and yellow circles exhibit a round protrusion with a small hole (like a doughnut), three lobes like a clover, and two parallel lobes corresponding to the C 60 molecules with a pentagon, hexagon, and 6:6 bond facing up, respectively [ 13 , 40 ]. We noticed that such types of orientational disorder also appeared in the R30° domains of C 60 grown on Au (111) [ 13 , 18 , 21 , 22 , 23 ] or Ge (111) surfaces [ 39 ].…”

“…A variety of C 60 monolayers grown on solid surfaces is critical for understanding and controlling the interface properties of fullerene-derived electronic and photovoltaic devices [ 1 , 2 , 3 ]. In the past decades, there have been a large number of investigations of C 60 monolayer structures grown on a wide range of metallic or semiconducting substrates such as Ag [ 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 ], Au [ 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 ], Cu [ 24 , 25 , 26 , 27 , 28 ], graphene [ 29 , 30 , 31 , 32 , 33 ], Si [ 34 , 35 , 36 ], Ge [ 37 , 38 , 39 ], or NaCl [ 40 ]. It was found that almost all monolayers of C 60 adopt a close-packed structure regardless whether the substrate is isotropic or anisotropic, metallic or nonmetallic.…”
