“…16−19 Recently, it was reported the observation of quasi-twodimensional chiral patterns in growth of C 60 -TCNQ by an ionized-cluster-beam (ICB) method. 20 Theoretical investigations have also been carried out on the broken symmetry of these patterns, 21 where, motivated by the presence of electric charged clusters in ICB deposition, the charged clusters are considered to be the crucial role that determines the chiral pattern formation. However, the actual growth mechanism and the role of charged clusters are still under debate.…”

Organic nanowires and quasi-two-dimensional chiral patterns of tetracyanoquinodimethane have been successfully generated by vacuum thermal evaporation. The nanowires and patterns were characterized by using atomic force microscopy and transmission electron microscopy. The influence of electric charged clusters, deposition rate, and substrate temperature were experimentally investigated. Contrary to previous reports, charged clusters are found to be unnecessary to the chiral pattern formation. It was shown that the nanowire and pattern formation should be mainly dominated by its special crystallization properties, though the effect of the growth conditions cannot be neglected.

“…Since its discovery in 1985, 1 C 60 has attracted great interest due not only to its unique structural and electronic properties 2,3 but also to its potential applications in various fields. [4][5][6][7][8] Extensive studies have been performed on the adsorption and growth properties of C 60 on different substrates, 2,3, [9][10][11][12][13][14] including metal surfaces such as Cu(111), 2 Ag(100), 3 Ag(001), 9 Au(111) 10 , and Ag(111) 10 and semiconductors like silicon 11 and GaAs. 12 On these flat surfaces, C 60 molecules usually adopt a closely packed hexagonal growth mode.…”

C60 molecules adsorbed on graphene/Ru(0001) substrate were investigated by scanning tunneling microscopy (STM) at 5 K. On high quality substrates, C60 molecules adopt a commensurate growth mode, leading to formation of a supramolecular structure with perfect periodicity and few defects. On under-annealed substrates with imperfections and domains, the molecules form the same closely packed hexagonal structures in spite of underlying corrugations, disorders or steps, indicating a weak molecule-substrate interaction—a conclusion that is also supported by DFT calculations. This system may be beneficial to the fabrication of carbon based devices and of other types of organic functional overlayers.

We present a new kind of organic complex system of electrical bistability, m-nitrobenzal malononitrile and diamine benzene ͑mNBMN-DAB͒, which can be employed as ultrahigh density data storage devices by scanning tunneling microscopy ͑STM͒. The mNBMN-DAB thin film was prepared on highly oriented pyrolitic graphite ͑HOPG͒ substrates using physical vacuum deposition method. A critical voltage pulse between the STM tip and the surface of the HOPG substrate can make marks on the thin films. The size of the marks is about 1.3 nm and the corresponding data storage density is larger than 10 13 bits/cm 2 . A new mechanism of the charge transfer in the system for the data storage is suggested. These results show a great potential of this type of organic composite systems in the application of the ultrahigh density data storage.
