Temperature Evolution of Quasi-one-dimensional C60 Nanostructures on Rippled Graphene

Abstract

We report the preparation of novel quasi-one-dimensional (quasi-1D) C60 nanostructures on rippled graphene. Through careful control of the subtle balance between the linear periodic potential of rippled graphene and the C60 surface mobility, we demonstrate that C60 molecules can be arranged into a quasi-1D C60 chain structure with widths of two to three molecules. At a higher annealing temperature, the quasi-1D chain structure transitions to a more compact hexagonal close packed quasi-1D stripe structure. This first experimental realization of quasi-1D C60 structures on graphene may pave a way for fabricating new C60/graphene hybrid structures for future applications in electronics, spintronics and quantum information.

Strain-Relief Patterns and Kagome Lattice in Self-Assembled C60 Thin Films Grown on Cd(0001)

“…In the fullerene family, C 60 was the first member to be created and most extensively discussed. C 60 molecules form various self-assembled structures when deposited on different types of substrate, such as Au [4][5][6][7][8][9], Ag [10][11][12][13][14], Cu [15,16], Pb [17], Pd [18], P [19], Al [20], graphene [21][22][23][24], WSe 2 [25], Si [26][27][28][29], and Ge [30][31][32]. Many results indicate that C 60 molecules are easy to nucleate at the terrace edge and may form a close-packed structure under appropriate conditions, regardless of the types of substrate, such as the 2 √ 3 × 2 √ 3 R30 • domain on Au(111) [33,34] and the 4 × 4 superstructure on graphene/Cu(111) [22].…”

The effect of the occurrence of a magnetic field of a current loop in hybrid graphene / C60 carbon systems

“…Various devices of molecular electronics and nanoelectronics have been proposed based on graphene / C 60 films, including mid-infrared photodetector [2], ultra-thin, flexible solar cells [3], vertical field-effect transistors [4,5], supercapacitors [6]. In a real experiment, the deposition of C 60 films on a graphene substrate is carried out using the well-proven thermal evaporation method [7,8] or spray coating method [5,6]. Investigations of the properties of this hybrid material are intensively developing at the present.…”

Zero-temperature magnetic response of small fullerene molecules at the classical and full quantum limit

“…Perhaps the most representative fullerene molecule is the truncated icosahedron [19][20][21][22][23][24][25], which has the spatial symmetry of the icosahedral group I h [26]. The truncated icosahedron becomes superconducting when doped with alkali metals [27].…”
